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This advisory has been withdrawn because it is a duplicate of GHSA-9528-x887-j2fp.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

Attackers who can reach the webhook endpoint can exploit this to forge inbound webhook events by repeatedly attempting authentication without throttling.
