Summary
OpenClaw: Message action attachment hydration bypasses local media root checks when sandboxRoot is unset
Details

Impact

sendAttachment and setGroupIcon message actions could hydrate media from local absolute paths when sandboxRoot was unset, bypassing intended local media root checks. This could allow reads of arbitrary host files reachable by the runtime user when an authorized message-action path was triggered.

Affected Packages / Versions

  • Package: openclaw (npm)
  • Latest published npm version at triage: 2026.2.23
  • Vulnerable: <= 2026.2.23
  • Patched in code: >= 2026.2.24 (planned next release)

Remediation

Upgrade to openclaw 2026.2.24 or later once published.

Fix Commit(s)

  • 270ab03e379f9653e15f7033c9830399b66b7e51

Release Process Note

patched_versions is pre-set to the planned next release (>= 2026.2.24). Once that npm release is published, this advisory can be published without further field edits.

OpenClaw thanks @GCXWLP for reporting.

Publication Update (2026-02-25)

openclaw@2026.2.24 is published on npm and contains the fix commit(s) listed above. This advisory now marks >= 2026.2.24 as patched.
