Description

OpenClaw versions 2026.4.9 before 2026.4.10 contain a sender policy bypass vulnerability in the outbound host-media attachment read helper that allows unauthorized local file disclosure. Attackers with denied read access via toolsBySender or group policy can trigger host-media attachment loading to bypass sender and group-scoped authorization boundaries and retrieve readable local files through the outbound media path.
