Summary

Duplicate Advisory: OpenClaw's Nextcloud Talk webhook missing rate limiting on shared secret authentication

Details

Duplicate Advisory

This advisory has been withdrawn because it is a duplicate of GHSA-9528-x887-j2fp. This link is maintained to preserve external references.

Original Description

OpenClaw before 2026.3.28 contains a missing rate limiting vulnerability in the Nextcloud Talk webhook authentication that allows attackers to brute-force weak shared secrets. Attackers who can reach the webhook endpoint can exploit this to forge inbound webhook events by repeatedly attempting authentication without throttling.
