Aliases CVE-2026-33581
Summary OpenClaw's message tool media parameter bypasses tool policy filesystem isolation ## Summary The message tool accepted `mediaUrl` and `fileUrl` aliases without applying the same sandbox localRoots validation as the canonical media path handling. ## Impact A caller constrained to sandbox media roots could read arbitrary local files by routing them through the alias parameters. ## Affected Component `src/infra/outbound/message-action-params.ts, src/infra/outbound/message-action-runner.ts` ## Fixed Versions - Affected: `< 2026.3.24` - Patched: `>= 2026.3.24` - Latest stable `2026.3.28` contains the fix. ## Fix Fixed by commit `1d7cb6fc03` (`fix: close sandbox media root bypass for mediaUrl/fileUrl aliases`). OpenClaw thanks @AntAISecurityLab for reporting.
