OpenClaw's message tool media parameter bypasses tool policy filesystem isolation
Packages
Details
As written in the advisory (Markdown source, shown as plain text).
## 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.
