Description
OpenClaw versions prior to 2026.2.22 contain an authorization bypass vulnerability in the toolsBySender group policy matching that allows attackers to inherit elevated tool permissions through identifier collision attacks. Attackers can exploit untyped sender keys by forcing collisions with mutable identity values such as senderName or senderUsername to bypass sender-authorization policies and gain unauthorized access to privileged tools.
