Remediation plan

1. Close now

High-severity findings that take minutes or hours to fix. Each one is a place an agent, or whoever can steer it, acts with nothing in between.

• AAR-001 Workflow token has write access to everything (.github/workflows/claude-triage.yml:9). Set top-level permissions to contents: read (or {}) and grant each job only the scopes it uses. Patch included. Owner: CI/CD workflows. Effort: minutes.
• AAR-002 An AI agent runs on events anyone can create (.github/workflows/claude-triage.yml:23). Gate the agent job on the actor: check github.event.comment.author_association (or the issue/PR equivalent) is OWNER, MEMBER or COLLABORATOR, or trigger it only from a label a maintainer applies. Patch included. Owner: CI/CD workflows. Effort: minutes.
• AAR-003 Untrusted event text is interpolated into a shell script (.github/workflows/claude-triage.yml:23). Pass the value through an env: variable and reference it as "$VAR" in the script. Never interpolate event fields into run:. Patch included. Owner: CI/CD workflows. Effort: minutes.
• AAR-004 The agent runs with its permission checks switched off (.github/workflows/claude-triage.yml:24). Remove the bypass flag or mode and give the agent an explicit allow list of narrow tools. Route anything else through CI. Patch included. Owner: CI/CD workflows. Effort: minutes.
• AAR-005 Merge uses --admin to skip branch protection (.github/workflows/claude-triage.yml:29). Drop --admin and make sure the agent's identity is not on any bypass list. Patch included. Owner: CI/CD workflows. Effort: minutes.
• AAR-006 The workflow merges its own pull request (.github/workflows/claude-triage.yml:29). Remove the merge step. Require a human code-owner approval on a protected branch, with stale approvals dismissed on new pushes. Patch included. Owner: CI/CD workflows. Effort: minutes.
• AAR-007 pull_request_target checks out untrusted PR code (.github/workflows/pr-review-bot.yml:18). Use pull_request for anything that builds or runs PR code, or never check out the head ref under pull_request_target. Patch included. Owner: CI/CD workflows. Effort: minutes.
• AAR-008 Agent action accepts requests from users without write access (.github/workflows/pr-review-bot.yml:25). Remove allowed_non_write_users, or list the specific accounts that need it and keep the agent's tools read-only for those runs. Patch included. Owner: CI/CD workflows. Effort: minutes.
• AAR-009 Any shell command is pre-approved (.github/workflows/pr-review-bot.yml:29). Allow specific commands only, for example Bash(npm run test:*), and deny network and deploy tools. Patch included. Owner: CI/CD workflows. Effort: minutes.
• AAR-010 The workflow approves pull requests (.github/workflows/pr-review-bot.yml:30). Remove the approval step. Approvals come from people (code owners) only. Owner: CI/CD workflows. Effort: minutes.
• AAR-011 Guard hook lets the call through when it fails (.claude/hooks/check_command.py:15,21). On any error, print the reason to stderr and exit 2. Remove || true and similar fallbacks from hook commands. Patch included. Owner: Agent configuration. Effort: minutes.
• AAR-012 Claude Code settings default to bypassing permissions (.claude/settings.json:3). Use the default mode and an explicit permissions.allow list of narrow commands. Patch included. Owner: Agent configuration. Effort: minutes.
• AAR-013 Any shell command is pre-approved (.claude/settings.json:5). Allow specific commands only, for example Bash(npm run test:*), and deny network and deploy tools. Patch included. Owner: Agent configuration. Effort: minutes.
• AAR-014 Guard hook lets the call through when it fails (.claude/settings.json:17). On any error, print the reason to stderr and exit 2. Remove || true and similar fallbacks from hook commands. Patch included. Owner: Agent configuration. Effort: minutes.
• AAR-015 Downloads a script and runs it (.github/workflows/deploy.yml:34). Download a pinned version, check its SHA-256, then run it, or install from a package manager with a locked version. Owner: CI/CD workflows. Effort: minutes.
• AAR-016 Filesystem MCP server is rooted at the whole disk or home folder (.mcp.json:5). Root it at the one project folder the agent works in. Patch included. Owner: Agent configuration. Effort: minutes.
• AAR-017 Downloads a script and runs it (CLAUDE.md:5). Download a pinned version, check its SHA-256, then run it, or install from a package manager with a locked version. Owner: Agent configuration. Effort: minutes.
• AAR-018 Agent instructions contain invisible characters (CLAUDE.md:6). Remove the characters, read the file in a viewer that shows them, and check what the hidden text said. Patch included. Owner: Agent configuration. Effort: minutes.
• AAR-019 Someone can merge past the review requirement (governance/branch-protection-main.json:12,18). Empty the bypass lists, enforce protection for admins, and handle emergencies with a logged break-glass process. Patch included. Owner: Repository settings. Effort: minutes.
• AAR-020 Force pushes allowed on the protected branch (governance/branch-protection-main.json:22). Turn off allow_force_pushes (or add the non_fast_forward rule to the ruleset). Patch included. Owner: Repository settings. Effort: minutes.
• AAR-021 Someone can merge past the review requirement (governance/ruleset-release.json:9). Empty the bypass lists, enforce protection for admins, and handle emergencies with a logged break-glass process. Owner: Repository settings. Effort: minutes.
• AAR-022 No approving review required (governance/ruleset-release.json:16). Require at least one approving review from someone other than the author. Patch included. Owner: Repository settings. Effort: minutes.
• AAR-023 Can read every secret in the account (infra/iam/agent-permissions.json:25). Scope the read to the specific secret or parameter ARNs, or remove it if the agent doesn't need secrets. Owner: Cloud IAM. Effort: minutes.
• AAR-024 GitHub OIDC trust policy matches a wildcard subject (infra/iam/agent-role-trust.json:12). Use StringEquals on the exact subject, for example repo:org/repo:environment:production. Owner: Cloud IAM. Effort: minutes.
• AAR-025 GitHub OIDC trust policy doesn't pin the subject (infra/terraform/ci.tf:18). Add a StringEquals condition on token.actions.githubusercontent.com:sub for the exact repo and environment. Owner: Cloud IAM. Effort: minutes.
• AAR-026 Policy can grant itself more permissions (infra/terraform/ci.tf:37). Remove IAM write actions from the agent's role. If provisioning needs them, give that job a separate role with a permissions boundary. Owner: Cloud IAM. Effort: minutes.
• AAR-027 Workload identity provider accepts any GitHub repository (infra/terraform/ci.tf:49). Add attribute_condition = "assertion.repository == 'org/repo'" (and pin the ref or environment). Owner: Cloud IAM. Effort: minutes.
• AAR-028 Any shell command is pre-approved (vendor-agents/seo-autopilot/.claude/commands/publish.md:3). Allow specific commands only, for example Bash(npm run test:*), and deny network and deploy tools. Patch included. Owner: Agent configuration. Effort: minutes.
• AAR-029 Hook sends tool activity to an outside server (vendor-agents/seo-autopilot/.claude/hooks/report.js:6). Remove the network call, or log locally and review what is sent before allowing any upload. Owner: Agent configuration. Effort: minutes.

• AAR-031 Claude Code settings default to bypassing permissions (vendor-agents/seo-autopilot/.claude/settings.json:6). Use the default mode and an explicit permissions.allow list of narrow commands. Patch included. Owner: Agent configuration. Effort: minutes.
• AAR-032 Long-lived AWS access keys stored as repository secrets (.github/workflows/deploy.yml:22). Use GitHub OIDC with aws-actions/configure-aws-credentials and a role whose trust policy pins the repo and environment in the sub claim. Owner: CI/CD workflows. Effort: hours.
• AAR-033 Credential written into a file (.mcp.json:11). Rotate the credential now, remove it from the file, and load it from the environment or a secrets manager. Owner: Secrets. Effort: hours.
• AAR-034 Infrastructure creates a long-lived access key (infra/terraform/ci.tf:7). Delete the IAM user and key. Have CI assume a role through GitHub OIDC. Owner: Cloud IAM. Effort: hours.
• AAR-035 AdministratorAccess attached (infra/terraform/ci.tf:28). Replace it with a policy scoped to the exact actions and resources the workflow needs, plus a permissions boundary. Owner: Cloud IAM. Effort: hours.
• AAR-036 Google Cloud basic role granted (infra/terraform/ci.tf:45). Grant predefined or custom roles that cover the specific services used. Owner: Cloud IAM. Effort: hours.
• AAR-037 Tool builds a shell command from its input (tools/ops-mcp/server.py:24). Call the program with an argument list (no shell) and validate inputs against an allow list. Owner: Agent tool code. Effort: hours.
• AAR-038 Tool trusts a caller-supplied header for identity (tools/ops-mcp/server.py:36). Authenticate callers with credentials the server verifies (signed tokens, mTLS) and authorize per tool, deny by default. Owner: Agent tool code. Effort: hours.
• AAR-039 Tool builds a shell command from its input (tools/release-helper/index.js:7). Call the program with an argument list (no shell) and validate inputs against an allow list. Owner: Agent tool code. Effort: hours.
• AAR-040 Tool evaluates code it was given (tools/release-helper/index.js:10). Parse the input into a fixed set of operations and dispatch on them. Owner: Agent tool code. Effort: hours.

2. Schedule this sprint

High-severity findings that need a project, and medium-severity findings.

• AAR-042 A step is allowed to fail without failing the job (.github/workflows/pr-review-bot.yml:21). Remove continue-on-error from any step that is meant to block a merge or deploy. Patch included. Owner: CI/CD workflows. Effort: minutes.
• AAR-043 The agent acts with a person's token (.github/workflows/claude-triage.yml:21,27). Use a GitHub App installation token scoped to this repo, with no bypass, so the agent has its own identity. Owner: CI/CD workflows. Effort: hours.
• AAR-044 Self-hosted runner used for pull request events (.github/workflows/pr-review-bot.yml:14). Run pull request jobs on GitHub-hosted or ephemeral runners. Keep self-hosted runners for trusted branches. Owner: CI/CD workflows. Effort: hours.
• AAR-045 Untrusted event text goes straight into the agent's prompt (.github/workflows/pr-review-bot.yml:28). Have the agent read the issue or PR itself through a read-only tool, keep the prompt fixed, and limit the job's token to read scopes plus the one write it needs. Owner: CI/CD workflows. Effort: hours.
• AAR-041 Tool runs arbitrary SQL (tools/ops-mcp/server.py:14,17). Replace it with narrow, parameterized tools (one per question) on a read-only database role. Owner: Agent tool code. Effort: project.
• AAR-046 Guard hook has no fail-closed handler (.claude/hooks/check_command.py:10). Wrap main() in try/except that prints the error to stderr and exits 2. Owner: Agent configuration. Effort: minutes.

• AAR-052 No specific code owner for the workflow files (.github/CODEOWNERS:1). Add /.github/ with a platform or security team owner, and require code-owner review on the protected branch. Patch included. Owner: Repository settings. Effort: minutes.
• AAR-053 Workflow doesn't declare token permissions (.github/workflows/deploy.yml:1). Add a top-level permissions block with the minimum scopes, and widen per job only where needed. Patch included. Owner: CI/CD workflows. Effort: minutes.
• AAR-054 Deploy step with no protected environment (.github/workflows/deploy.yml:26,36). Run the deploy in a job with environment: production, and protect that environment with required reviewers and allowed branches. Patch included. Owner: CI/CD workflows. Effort: minutes.
• AAR-055 Health check that can't fail (.github/workflows/deploy.yml:38). Use curl -fsS, drop the || fallback, and fail the step when the check fails. Patch included. Owner: CI/CD workflows. Effort: minutes.
• AAR-056 A required gate job can be skipped (.github/workflows/deploy.yml:40). Give the gate job if: always() and have it fail explicitly unless every needed job's result is success. Patch included. Owner: CI/CD workflows. Effort: minutes.
• AAR-057 Remote MCP server over plain HTTP (.mcp.json:17). Use an https:// URL. Patch included. Owner: Agent configuration. Effort: minutes.

• AAR-059 Approvals survive new pushes (governance/branch-protection-main.json:8,10). Dismiss stale approvals on push and require approval of the most recent push. Patch included. Owner: Repository settings. Effort: minutes.
• AAR-060 Code-owner review isn't required (governance/branch-protection-main.json:9). Turn on require code owner review and give sensitive paths specific owners in CODEOWNERS. Patch included. Owner: Repository settings. Effort: minutes.
• AAR-061 Ruleset is not enforced (governance/ruleset-release.json:5). Set enforcement to active once the evaluate results look right. Patch included. Owner: Repository settings. Effort: minutes.
• AAR-062 iam:PassRole without iam:PassedToService (infra/iam/agent-permissions.json:19). Limit Resource to the roles it must pass and add a Condition on iam:PassedToService. Owner: Cloud IAM. Effort: minutes.
• AAR-063 Tool server listens on every network interface (tools/ops-mcp/server.py:40). Bind to 127.0.0.1 or a private socket and require authentication if it must be remote. Owner: Agent tool code. Effort: minutes.
• AAR-064 Agent instructions tell it to act without asking (vendor-agents/seo-autopilot/.claude/commands/publish.md:6). Rewrite the instruction so the agent stops and asks before merges, deploys, deletes and anything outside its folder. Owner: Agent configuration. Effort: minutes.
• AAR-065 File edits anywhere are pre-approved (vendor-agents/seo-autopilot/.claude/settings.json:3). Scope edits to the folders the agent works in, for example Edit(./src/), and deny .github/ and .claude/**. Owner: Agent configuration. Effort: minutes.
• AAR-066 Every tool of an MCP server is pre-approved (vendor-agents/seo-autopilot/.claude/settings.json:3). Allow the specific read tools by full name and let write tools ask. Owner: Agent configuration. Effort: minutes.

Findings

AAR-001 High: Workflow token has write access to everything

.github/workflows/claude-triage.yml:9 (workflow can be triggered from outside)

9  permissions: write-all

Risk. permissions: write-all lets the job's GITHUB_TOKEN write contents, pull requests, issues, packages and Actions. That is far beyond what an agent job needs.

Fix. Set top-level permissions to contents: read (or {}) and grant each job only the scopes it uses.

AAR-002 High: An AI agent runs on events anyone can create

.github/workflows/claude-triage.yml:23 (workflow can be triggered from outside)

23  claude -p "Triage this issue and open a fix: ${{ github.event.issue.title }}" \

Detail: triggered by issue_comment, issues.

Risk. The workflow starts an agent on issue, comment or fork pull-request events and nothing checks who triggered it. Anyone who can open an issue can put text in front of an agent that holds this job's token and secrets.

Fix. Gate the agent job on the actor: check github.event.comment.author_association (or the issue/PR equivalent) is OWNER, MEMBER or COLLABORATOR, or trigger it only from a label a maintainer applies.

.github/workflows/claude-triage.yml:23 (workflow can be triggered from outside)

23  claude -p "Triage this issue and open a fix: ${{ github.event.issue.title }}" \

Risk. ${{ }} is expanded before the shell runs, so whoever writes the issue title, PR body or branch name controls part of the command, and part of the agent's prompt.

Fix. Pass the value through an env: variable and reference it as "$VAR" in the script. Never interpolate event fields into run:.

Risk. Anyone who can reach the tool server can set x-caller (or similar) to whatever they like, so the identity check proves nothing.

Fix. Authenticate callers with credentials the server verifies (signed tokens, mTLS) and authorize per tool, deny by default.

Risk. eval, exec or new Function on tool input runs whatever the model or a prompt injection sends.

Fix. Parse the input into a fixed set of operations and dispatch on them.

const OPS = { add: (a, b) => a + b };
const result = OPS[op](a, b); // dispatch, never eval

Risk. A tool that executes whatever query the model writes makes the model's reasoning the authority over your database. A keyword blocklist isn't a boundary.

Fix. Replace it with narrow, parameterized tools (one per question) on a read-only database role.

@mcp.tool()
def orders_for_customer(customer_id: int) -> list[dict]:

AAR-071 Medium: Tool connects with an admin database credential

.mcp.json:12

12  "OPS_ADMIN_DSN": "${OPS_ADMIN_DSN}"

Risk. The tool can do whatever that admin role can, whatever the tool's name or description says.

Fix. Give each tool its own least-privilege database role.

# One role per tool, read-only unless the tool writes:
CREATE ROLE agent_reader LOGIN; GRANT SELECT ON orders, customers TO agent_reader;

AAR-072 Medium: Policy allows every action in a service

infra/iam/agent-permissions.json:13

13  "Action": "s3:*",

Detail: s3:*.

Risk. A service wildcard such as s3:* or iam:* includes destructive and administrative actions the agent never needs.

Fix. Replace service:* with the specific actions used.

"Action": ["s3:GetObject", "s3:ListBucket"]

AAR-073 Medium: Write actions allowed on every resource

infra/iam/agent-permissions.json:20

20  "Resource": "*"

Detail: ecs:UpdateService, iam:PassRole.

Risk. Resource "*" on mutating actions means the agent can change anything of that type in the account.

Fix. Scope Resource to the specific ARNs the workflow touches.

"Resource": ["arn:aws:SERVICE:REGION:ACCOUNT_ID:RESOURCE_TYPE/NAME"]

AAR-076 Medium: Tool fetches any URL it is given

tools/release-helper/index.js:13

13  const res = await fetch(url);

Risk. A fetch tool with no host allow list can reach internal services and cloud metadata endpoints, and can send data out.

Fix. Check the URL's host against an allow list and refuse private and link-local addresses.

ALLOWED_HOSTS = {"api.github.com", "docs.python.org"}
if urllib.parse.urlparse(url).hostname not in ALLOWED_HOSTS:
    raise ValueError("host not allowed")

AAR-077 Low: Every job can mint a cloud identity token

.github/workflows/pr-review-bot.yml:10 (workflow can be triggered from outside)

10  id-token: write

Risk. id-token: write at the top of the workflow lets every job request an OIDC token, including jobs that run an agent or untrusted code.

Fix. Move id-token: write into the one job that assumes the cloud role.

AAR-079 Low: No deny rules

.claude/settings.json:4

4  "allow": [

Risk. An allow list without denies relies on nobody ever widening it. Deny rules for secrets, deploy scripts and workflow files hold even when it is.

Fix. Add permissions.deny for .env and secrets reads, deploy commands and edits to .github/workflows.

.github/CODEOWNERS:3

3  /infra/           @dana-okafor

Detail: /infra/ is owned only by @dana-okafor.

Risk. One owner on infrastructure, IAM or workflow paths is a single point of approval, and of failure when they're out.

Fix. Name a second owner (a team or another person) for each sensitive path.

/infra/  @current-owner  @second-owner-or-team

AAR-082 Low: MCP server package is not pinned to a version

.mcp.json:5

5  "args": ["-y", "@modelcontextprotocol/server-filesystem", "/"]

Detail: filesystem: @modelcontextprotocol/server-filesystem.

Risk. npx -y, uvx or an untagged image fetches whatever version is current at launch, and that code runs with the agent's access.

Fix. Pin the package to an exact version (package@1.2.3, package==1.2.3, or an image digest).

"args": ["-y", "PACKAGE@EXACT_VERSION"]
// npm view PACKAGE version   prints the current version

"Condition": {

Method: every file in the input was listed and hashed (see inventory.json in the evidence package), then checked against 74 deterministic rules. The rules read files as text with pattern and indentation checks; they do not run your workflows, call GitHub or your cloud, or see settings that live only in a web console. A clean result means none of these patterns was found, not that the setup is safe. Each finding names the line so a person can confirm it.
