Identity & Access, Data Breach & Exfiltration

OpenClaw versions 2026.4.9 before 2026.4.10 contain a sender policy bypass vulnerability in the outbound host-media attachment read helper. The vulnerability allows unauthorized local file disclosure where attackers with denied read access via toolsBySender or group policy can trigger host-media attachment loading. This enables bypassing sender and group-scoped authorization boundaries to retrieve readable local files through the outbound media path. The vulnerability affects file access controls and authorization mechanisms in OpenClaw installations.
