Description

OpenClaw before 2026.5.19 contains an authorization bypass vulnerability in message read actions that skips channel allowlist checks. Lower-trust callers can request messages from channels not intended for them by exploiting insufficient validation in the affected feature, potentially exposing sensitive channel messages.
