A complete self-contained reproduction is inlined below — copy the four files into a directory and run `docker compose up`, plus a single-file probe that runs against Node directly. Locally validated against HEAD `291817c`.\n\n## Summary\n\nNovu's shared SSRF guard `validateUrlSsrf(url)` is used before server-side requests to user-configured URLs. The guard resolves hostnames and blocks a regex list of private/reserved IP ranges, but it does not block `100.64.0.0/10` shared address space. As a result, Novu features protected by this guard can still send server-side requests to destinations such as `100.100.100.200` (Alibaba Cloud metadata service) and any other service reachable in `100.64.0.0/10`.\n\n## Affected code\n\nGuard:\n\n- `libs/application-generic/src/utils/ssrf-url-validation.ts`\n  - `isPrivateIp(...)` regex list at lines 9-28\n  - DNS resolution and address validation at lines 55-72\n\nProduct call-sites:\n\n- Workflow HTTP request step: `apps/worker/src/app/workflow/usecases/send-message/execute-http-request-step.usecase.ts` — calls `validateUrlSsrf(url)` at line 149, then uses `HttpClientService` ","public_affected_ranges":["< 3.17.0"]}],"null_published_at":"2026-11-04T10:04:27.938Z","source_updated_at":"2026-07-28T14:59:24.000Z","source_disclosed_at":"2026-07-28T14:59:22.000Z","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":"2026-11-03T09:59:04.660Z"}],"next_cursor":null,"snapshot_revision":"42594"}
