Description
OpenClaw versions prior to 2026.2.22 contain an authorization bypass vulnerability in the Feishu allowFrom allowlist implementation that accepts mutable sender display names instead of enforcing ID-only matching. An attacker can set a display name equal to an allowlisted ID string to bypass authorization checks and gain unauthorized access.
