Vulnerability from fkie_nvd - Published: 2026-03-05 22:16 - Updated: 2026-03-11 16:18
Severity ?
5.3 (Medium) - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N
Summary
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.
