🔐 Daily Secrets Analysis Report

Date: 2026-09-02
Workflow Files Analyzed: 298
Run: 33662377707

📊 Executive Summary

• Total Secret References: 10,757 (secrets.*) — ▲ +30 vs 2026-09-01
• GitHub Token References: 2,217 (github.token) — ▲ +7 vs 2026-09-01
• Unique Secret Types: 40 — ▲ +1 vs 2026-09-01
• Job-Level Usage: 0 (0%)
• Step-Level Usage: 4,922 (100%)

🛡️ Security Posture

✅ Redaction System: 298/298 workflows have redaction steps (100% coverage)
✅ Token Cascades: 1,008 instances of fallback chains (GH_AW_GITHUB_MCP_SERVER_TOKEN || secrets.GH_AW_GITHUB_TOKEN || secrets.GITHUB_TOKEN)
✅ Permission Blocks: 298 explicit permission definitions (1 per workflow, 100% coverage)
✅ No template injection: TestCompiledLockFiles_NoGitHubEventExpressionsInRunScripts passed — no direct github.event.* interpolation in run: scripts
✅ No secret exposure in outputs: TestCompiledLockFiles_NoSecretsInOutputs passed — no secrets found in job or workflow_call outputs

🎯 Key Findings

1. Steady, proportional growth: The workflow count grew by 1 (297→298), and secret references grew by +30 (0.28%), roughly in line with the new workflow — no disproportionate spike in secret usage.
2. 100% redaction and step-level scoping maintained: Every compiled workflow continues to include a redaction step, and 100% of secret references remain at the step level rather than job-level env: blocks, keeping blast radius minimal.
3. Token cascade pattern continues to dominate: GITHUB_TOKEN (5,327) and GH_AW_GITHUB_TOKEN (4,593) remain the top two secrets by far, with the standard fallback chain used 1,008 times (+3 vs yesterday) for MCP server auth.
4. One new unique secret type appeared (39→40) — likely tied to the newly added workflow; no anomalous or unexpected secret names were observed in the full inventory (Datadog, Grafana, Sentry, AI-engine keys, and internal GH_AW_* tokens all present as before).
5. Both automated security regression tests pass clean: no template injection risk via github.event.* in run scripts, and no secrets leaking into job/workflow_call outputs.

💡 Recommendations

1. Maintain 100% redaction coverage as new workflows are added — this remains a hard invariant (298/298) and should stay enforced by the compiler.
2. Continue monitoring token cascade usage to ensure GH_AW_GITHUB_MCP_SERVER_TOKEN (the most restrictive token) is preferred wherever configured, minimizing unnecessary fallback to broader GITHUB_TOKEN scope.
3. No action needed on template injection or output exposure — both Go regression tests (TestCompiledLockFiles_NoGitHubEventExpressionsInRunScripts, TestCompiledLockFiles_NoSecretsInOutputs) continue to pass; keep them as CI guards.
4. Investigate the new unique secret type introduced since 2026-09-01 to confirm it follows existing naming/scoping conventions (e.g. GH_AW_* prefix for internal tokens).
