Affected: OpenClaw

OpenClaw before 2026.3.24 contains a sandbox bypass vulnerability in the message tool that allows attackers to read arbitrary local files by using mediaUrl and fileUrl alias parameters that bypass localRoots validation. Remote attackers can exploit this by routing file requests through unvalidated alias parameters to access files outside the intended sandbox directory.

 https://vulnerability.circl.lu/vuln/ghsa-v8wv-jg3q-qwpq GHSA-v8wv-jg3q-qwpq — OpenClaw's message tool media parameter bypasses tool policy filesystem isolation 2026-09-28T18:37:13.004617+00:00

Affected: npm: openclaw

## 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.
