Description

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.

Detection & mitigation playbook

Open-source dependency

  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for openclaw, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update openclaw to 2026.3.24 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-v8wv-jg3q-qwpq is resolved across your whole dependency graph.

  3. Workarounds

    Resolve every user-supplied path to its canonical form and reject anything that escapes the intended directory, and run the component under an account that has no read or write access outside the directory it legitimately serves.
