What it is

OpenClaw before 2026.9.5 contains an incorrect authorization vulnerability in the Gateway's local media root allowlist that breaks filesystem isolation between sandboxed sessions. Sandboxed sessions or untrusted content can cause the Gateway to read files from sibling session sandboxes or shared workspace directories through media pipeline functions that fail to restrict reads to the active session.
