Description
OpenClaw before 2026.4.24 contains an authorization bypass vulnerability in the MCP loopback feature that allows non-owner callers to skip owner-only tool policies and before-tool-call hooks. Attackers can invoke owner-only behavior through the affected loopback path to execute restricted tools when the feature is enabled and reachable.
