OpenClaw: Telegram Webhook Missing Guess Rate Limiting Enables Brute-Force Guessing of Weak Webhook Secret

view advisory published 2026-03-27Licence: CC-BY-4.0

## Summary Telegram Webhook Missing Guess Rate Limiting Enables Brute-Force Guessing of Weak Webhook Secret ## Affected Packages / Versions - Package: `openclaw` - Affected versions: `<= 2026.3.24` - First patched version: `2026.3.25` - Latest published npm version at verification time: `2026.3.24` ## Details Telegram webhook auth previously rejected bad secrets but did not throttle repeated guesses, allowing brute-force attempts against weak webhook secrets. Commit `c2c136ae9517ddd0789d742a0fdf4c10e8c729a7` adds repeated-guess throttling before auth failure responses. Verified vulnerable on tag `v2026.3.24` and fixed on `main` by commit `c2c136ae9517ddd0789d742a0fdf4c10e8c729a7`. ## Fix Commit(s) - `c2c136ae9517ddd0789d742a0fdf4c10e8c729a7` ## Release Process Note `2026.3.25` is the next planned OpenClaw release version in `package.json`. This advisory is being published ahead of that npm release so the draft is no longer blocked; once `2026.3.25` is published, the structured patched-version metadata will match the released artifact.
