CVE-2026-41376 Details
Description
OpenClaw before 2026.3.31 contains an allowlist bypass vulnerability in Matrix thread root and reply context handling that fails to properly validate message senders. Attackers can fetch thread-root and reply context messages that should be filtered by sender allowlists, bypassing access controls.
A vulnerability allowing allowlist bypass in OpenClaw versions prior to 2026.3.31 has been identified. This issue arises in the handling of Matrix thread root and reply contexts, where the validation of message senders is inadequate. As a result, attackers can access thread-root and reply context messages that should be restricted by sender allowlists, effectively circumventing access controls.
Users can update to OpenClaw version 2026.3.31 or later, where this vulnerability has been patched.
