BREW-openclaw-cli-CVE-2026-35628 — OpenClaw: Telegram Webhook Missing Guess Rate Limiting Enables Brute-Force Guessing of Weak Webhook Secret

Affected: Homebrew: openclaw-cli

## 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.

OpenClaw before 2026.3.25 contains a missing rate limiting vulnerability in Telegram webhook authentication that allows attackers to brute-force weak webhook secrets. The vulnerability enables repeated authentication guesses without throttling, permitting attackers to systematically guess webhook secrets through brute-force attacks.
