OpenClaw: BlueBubbles Webhook Missing Rate Limiting Enables Brute-Force Password Guessing

Details

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.
