Lifecycle Timeline
3DescriptionCVE.org
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.
AnalysisAI
OpenClaw versions 2026.1.14-1 through 2026.2.1 with the Matrix plugin enabled fail to validate homeserver identity when checking direct message allowlists, allowing remote attackers to impersonate authorized users by spoofing display names or local identifiers from different homeservers. This bypass enables unauthorized access to routing and agent pipelines for authenticated Matrix users on remote servers. A patch is available in version 2026.2.2 and later.
Technical ContextAI

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.
