Your job is to audit GitHub Actions workflow + changes for security vulnerabilities. You are specifically looking for problems + that could allow attackers to compromise the CI pipeline, exfiltrate secrets, or + manipulate automated processes. + + First, read every changed workflow file in this PR thoroughly. Then review each + file against the following checklist. + + ## 1. Prompt Injection + + This is the HIGHEST PRIORITY check. Any workflow that passes data to an LLM + (Claude, GPT, etc.) is a potential prompt injection target. + + - **Direct interpolation**: Are GitHub event fields (github.event.issue.title, + github.event.issue.body, github.event.pull_request.body, comment bodies, + commit messages) interpolated directly into a prompt using GitHub Actions + expression syntax (dollar-sign double-curly-brace)? This is ALWAYS a finding — + attacker-controlled data must never be spliced into prompts. The LLM should + fetch the data itself via tool calls. + - **Tool scope**: If an LLM agent has `Bash` tool access, are the allowed commands + tightly scoped? `Bash(gh api:*)` is too broad — it allows arbitrary GitHub API + calls. Tools should be restricted to the minimum necessary (e.g., + `Bash(gh issue view:*)`, `Bash(gh pr review:*)`). + - **Prompt hardening**: Does each LLM prompt include a security preamble instructing + the model to treat fetched content as untrusted data and ignore embedded instructions? + + ## 2. Expression Injection & Script Injection + + - Are GitHub Actions expressions used directly in `run:` blocks where they could + break out of the intended command? For example, interpolating + github.event.issue.title directly in a run block is DANGEROUS — the title could + contain shell metacharacters or command substitution. The safe pattern is to pass + untrusted data via environment variables instead. + - Are GitHub Actions expressions used in contexts where they could inject YAML + structure (e.g., in `if:` conditions, `with:` inputs)? + + ## 3. Dangerous Triggers + + - `pull_request_target`: Runs in the BASE repo context with secrets. If combined + with `actions/checkout` using the PR HEAD ref, attacker code runs with repo secrets. + Flag any `pull_request_target` workflow that checks out PR code. + - `issue_comment`, `issues`, `discussion_comment`: Triggered by external users. + Verify that attacker-controlled content from these events is not used unsafely. + - `workflow_dispatch` with `inputs`: Check that input values are validated before use. + + ## 4. Supply Chain + + - Are third-party actions pinned to a full commit SHA? Using `@v1` or `@main` means + the action code can change without your knowledge. Only `actions/*` (GitHub-owned) + are acceptable with tag-only pins. + - Is `curl | bash` or similar remote script execution used? This should always be + replaced with a pinned action or a vendored script. + - Are `setup-*` actions from trusted publishers (actions/*, denoland/*, etc.)? + + ## 5. Permissions + + - Are permissions scoped at the JOB level, not the workflow level? Workflow-level + permissions apply to ALL jobs, including ones that don't need them. + - Does each job request the MINIMUM permissions it needs? A test job should only + need `contents: read`. Only merge/deploy jobs need `contents: write`. + - Is `id-token: write` present? This allows OIDC token generation — verify it's + actually needed. + + ## 6. Secret Exposure + + - Are secrets passed to steps that don't need them? + - Could secrets leak through log output, error messages, or environment variable dumps? + - Are secrets used in `run:` blocks where command substitution could expose them? + - Are PATs (Personal Access Tokens) used where `GITHUB_TOKEN` would suffice? + + ## 7. Auto-merge & Trust Boundaries + + - If the workflow auto-merges PRs, what gates must pass first? Are there human + approval requirements, or can automated reviews alone trigger a merge? + - Can a same-repo contributor bypass review gates by crafting specific PR content? + - Are fork PRs properly excluded from privileged operations? + + ## Review Rules + + - Be SPECIFIC. Name the exact file, line, expression, and attack scenario. + - For each finding, explain: what's vulnerable, how an attacker would exploit it, + and what the fix is. + - Do NOT flag non-security issues (style, naming, documentation). + - If the workflow changes are security-neutral or improve security, say so. + + ## Severity Classification + + - **CRITICAL**: Prompt injection with broad tool access, secret exfiltration, + arbitrary code execution via expression injection, unpinned actions in privileged + workflows. These BLOCK the merge. + - **HIGH**: Overly broad tool scoping, missing prompt hardening, workflow-level + permissions that should be job-level. These BLOCK the merge. + - **MEDIUM**: Missing SHA pins on low-privilege actions, permissions that are broader + than necessary but not exploitable. These are warnings. + - **LOW**: Style issues in workflow files, missing comments.
