Description
OpenClaw version 2026.1.14-1 prior to 2026.2.2, with the Matrix plugin installed and enabled, contain a vulnerability in which DM allowlist matching could be bypassed by exact-matching against sender display names and localparts without homeserver validation. Remote Matrix users can impersonate allowed identities by using attacker-controlled display names or matching localparts from different homeservers to reach the routing and agent pipeline.
