🔐 Daily Secrets Analysis Report

Date: 2026-08-26
Workflow Files Analyzed: 294
Run: https://github.com/github/gh-aw/actions/runs/32998160173

📊 Executive Summary

• Total Secret References: 10,340 (secrets.*)
• GitHub Token References: 2,200 (github.token)
• Unique Secret Types: 39

🛡️ Security Posture

✅ Redaction System: 294/294 workflows have redact_secrets steps (100%)
✅ Token Cascades: 1,024 instances of GH_AW_GITHUB_MCP_SERVER_TOKEN || secrets.GH_AW_GITHUB_TOKEN || secrets.GITHUB_TOKEN fallback chains
✅ Permission Blocks: 294 explicit permissions: definitions (1 per workflow — least-privilege scoping present everywhere)

Automated security tests (Go, pkg/workflow):

• ✅ TestCompiledLockFiles_NoGitHubEventExpressionsInRunScripts — PASS. No direct github.event.* interpolation found in executable run: scripts (template injection risk mitigated).
• ✅ TestCompiledLockFiles_NoSecretsInOutputs — PASS. No secrets.* values are exposed via job or workflow-call outputs:.

🎯 Key Findings

1. Universal redaction coverage: All 294 compiled workflows include a redact_secrets step, ensuring runtime secret values are scrubbed from logs before upload.
2. Token usage is dominated by GitHub auth: GITHUB_TOKEN (5,282), GH_AW_GITHUB_TOKEN (4,560), and GH_AW_GITHUB_MCP_SERVER_TOKEN (1,937) together account for the vast majority of all secret references — consistent with the standard token-cascade pattern used for MCP server authentication.
3. Observability secrets present at moderate scale: OpenTelemetry/Sentry and Grafana authorization/endpoint secrets (GH_AW_OTEL_SENTRY_AUTHORIZATION, GH_AW_OTEL_SENTRY_ENDPOINT, GH_AW_OTEL_GRAFANA_AUTHORIZATION, GH_AW_OTEL_GRAFANA_ENDPOINT) appear in roughly 250–750 places each, reflecting the optional telemetry integration used by a subset of workflows rather than a universal one.
4. No template-injection or output-leak findings: both deterministic Go safety tests passed clean — no regressions detected this run.
5. This is the first run with saved historical stats — no prior-day snapshot exists yet, so trend deltas are not available. Baseline stats have been captured for tomorrow's comparison.

💡 Recommendations

1. Continue enforcing the two Go safety tests (NoGitHubEventExpressionsInRunScripts, NoSecretsInOutputs) as required CI gates — they are the primary automated defense against template injection and secret leakage via outputs.
2. Monitor the token-cascade count over time: a sudden drop could indicate a workflow bypassing the standard GH_AW_GITHUB_MCP_SERVER_TOKEN || secrets.GH_AW_GITHUB_TOKEN || secrets.GITHUB_TOKEN fallback, which should be flagged for review.
3. Track unique secret type growth (currently 39): new secret types introduced by workflow changes should be reviewed for necessity and scoping before merge.

📈 Trends

No historical snapshot from a previous run was found, so day-over-day trends are not yet available. Baseline stats (294 workflows, 10,340 secret refs, 2,200 token refs, 39 unique secret types, 294 workflows with redaction, 1,024 cascade usages) have been recorded for comparison in tomorrow's report.
