In runtime validation, this endpoint was reachable without auth, triggered outbound POST requests to an attacker-controlled server, and reflected the full remote response body to the caller (`tokenInfo`), confirming non-blind SSRF and credential secret exfiltration.\n\n### Details\n\nThe vulnerability is in `dist/routes/oauth2/index.js` (container runtime build), under path prefix `/api/v1/oauth2-credential`.\n\nConfirmed in runtime code:\n\n1. **Unauthenticated route via whitelist**\n   - `dist/utils/constants.js` includes:\n     - `/api/v1/oauth2-credential/callback`\n     - `/api/v1/oauth2-credential/refresh`\n   - `dist/index.js` auth middleware uses:\n     - `const isWhitelisted = whitelistURLs.some((url) => req.path.startsWith(url))`\n   - Therefore `/api/v1/oauth2-credential/refresh/:credentialId` is treated as whitelisted.\n\n2. **User-controlled SSRF target**\n   - In refresh handler (`dist/routes/oauth2/index.js`","public_affected_ranges":["<= 3.1.2"]}],"null_published_at":"2026-11-03T10:03:26.533Z","source_updated_at":"2026-08-04T14:20:51.000Z","source_disclosed_at":"2026-08-04T14:20:49.000Z","is_synthetic_fixture":false,"null_last_reviewed_at":null,"public_change_summary":"First indexed by Null; source disclosure date is shown separately.","null_first_observed_at":"2026-11-03T09:58:33.950Z"}],"next_cursor":null,"snapshot_revision":"42594"}
