supply-chain-guard Scan Report

WARNING: Findings were detected.

Canonical JSON report: 4 reportable finding(s).

## 🛡️ supply-chain-guard Scan Report

| Property | Value |
|----------|-------|
| Target | `.` |
| Type | directory |
| Time | 2026-08-02T09:16:59.258Z |
| Duration | 1042ms |
| **Risk Score** | **14/100** (MEDIUM) |

### Summary

Scanned 69 of 76 files.

🟡 2 medium | 🔵 2 low

### Findings

#### 🟡 [MEDIUM] Workflow requests OIDC id-token:write permission. If combined with unreviewed third-party actions or outbound curl, an attacker can steal the OIDC token to impersonate the workflow's cloud identity.

- **Rule:** `GHA_OIDC_WRITE_PERM`
- **File:** `.github/workflows/ci.yml:49`
- **Match:** `id-token: write`
- **Recommendation:** Audit all steps in this workflow when id-token:write is set. Ensure no third-party action or run step can exfiltrate the OIDC token. Scope permissions as narrowly as possible.

#### 🟡 [MEDIUM] Workflow "ci.yml" accesses secrets and has network egress. Verify secrets are not sent to external endpoints.

- **Rule:** `WORKFLOW_SECRET_TO_UPLOAD_PATH`
- **File:** `.github/workflows/ci.yml`
- **Recommendation:** Audit this workflow for secret-to-network paths. Minimize secret scoping.

#### 🔵 [LOW] Action "homeofe/supply-chain-guard@v5" uses a version tag instead of a commit SHA. Tags can be force-pushed to point to different commits.

- **Rule:** `GHA_TAG_NOT_SHA`
- **File:** `.github/workflows/supply-chain-guard.yml:21`
- **Match:** `homeofe/supply-chain-guard@v5`
- **Recommendation:** Consider pinning this action to a full commit SHA for maximum security. Tags can be moved to point to malicious code.

#### 🔵 [LOW] Action "homeofe/supply-chain-guard@v5" is from third-party owner "homeofe". Third-party actions can be compromised.

- **Rule:** `GHA_THIRD_PARTY_ACTION`
- **File:** `.github/workflows/supply-chain-guard.yml:21`
- **Match:** `homeofe/supply-chain-guard@v5`
- **Recommendation:** Pin "homeofe/supply-chain-guard@v5" to a specific commit SHA and audit the action source code before use.

### Recommendations

- Review the listed findings and assess whether they represent legitimate functionality or potential threats.
