Duplicate Advisory

This advisory has been withdrawn because it is a duplicate of GHSA-fcvx-5cxc-v5p8. This link is maintained to preserve external references.

Original Description

OpenClaw before 2026.5.12 contains a notification bypass vulnerability allowing Slack reaction events to enter the agent pipeline despite disabled reaction notifications.
