# API Reference: Securing GitHub Actions Workflows
|
|
|
|
## Security Checks
|
|
|
|
| Check | Risk | Severity |
|
|
|-------|------|----------|
|
|
| Unpinned actions (mutable tags) | Supply chain attack via tag overwrite | Medium |
|
|
| Missing permissions block | Inherits overly broad defaults | Medium |
|
|
| write-all permissions | Excessive token scope | High |
|
|
| Script injection in run steps | Code execution via PR title/body | High |
|
|
| pull_request_target trigger | Fork code runs with base permissions | High |
|
|
| Secrets in workflow logs | Credential exposure | Critical |
|
|
|
|
## Dangerous Expression Contexts
|
|
|
|
| Context | Risk |
|
|
|---------|------|
|
|
| `github.event.pull_request.title` | Attacker-controlled PR title |
|
|
| `github.event.pull_request.body` | Attacker-controlled PR body |
|
|
| `github.event.issue.title` | Attacker-controlled issue title |
|
|
| `github.event.comment.body` | Attacker-controlled comment |
|
|
| `github.head_ref` | Attacker-controlled branch name |
|
|
|
|
## SHA Pinning Format
|
|
|
|
| Format | Security |
|
|
|--------|----------|
|
|
| `actions/checkout@v4` | Insecure - mutable tag |
|
|
| `actions/checkout@b4ffde65f...` | Secure - immutable SHA |
|
|
|
|
## Permission Scopes
|
|
|
|
| Scope | Values |
|
|
|-------|--------|
|
|
| contents | read, write |
|
|
| actions | read, write |
|
|
| deployments | read, write |
|
|
| id-token | write (for OIDC) |
|
|
| security-events | write |
|
|
| pull-requests | read, write |
|
|
|
|
## Python Libraries
|
|
|
|
| Library | Version | Purpose |
|
|
|---------|---------|---------|
|
|
| `yaml` | PyYAML >=6.0 | Parse workflow YAML |
|
|
| `re` | stdlib | Pattern matching |
|
|
| `json` | stdlib | Report output |
|
|
| `pathlib` | stdlib | File discovery |
|
