CVE-2026-28471 is a medium-severity vulnerability rated 6.3/10 on the CVSS scale. 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.. EPSS estimates a 0.23% chance of exploitation in the next 30 days.
