2026-10-06T04:00:58.090811+00:00

Affected: Homebrew: openclaw-cli

## Summary

BlueBubbles Webhook Missing Guess Rate Limiting Enables Brute-Force Guessing of Weak Webhook Password

## 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

BlueBubbles webhook auth previously rejected wrong passwords without throttling repeated guesses, allowing brute-force attempts against weak webhook passwords. Commit `5e08ce36d522a1c96df2bfe88e39303ae2643d92` adds repeated-guess throttling before auth failure responses.

Verified vulnerable on tag `v2026.3.24` and fixed on `main` by commit `5e08ce36d522a1c96df2bfe88e39303ae2643d92`.

OpenClaw before 2026.3.25 contains a missing rate limiting vulnerability in webhook authentication that allows attackers to brute-force weak webhook passwords without throttling. Remote attackers can repeatedly submit incorrect password guesses to the webhook endpoint to compromise authentication and gain unauthorized access.
