GHSA-qcc4-p59m-p54m: OpenClaw: Sandbox dangling-symlink alias handling could bypass workspace-only write boundary

Summary

A sandbox boundary-validation gap in symlink alias handling allowed certain workspace-only write paths to be treated as in-boundary even when they could resolve outside the workspace/sandbox root.

Affected Packages / Versions

• Package: npm openclaw
• Affected versions: <= 2026.2.25
• Latest published npm version included in affected range: 2026.2.25 (checked on February 26, 2026)
• Patched version (pre-set for release): 2026.2.26

Technical Details

In affected versions, dangling symlink hops could be accepted during boundary checks under missing-target conditions. For workspace-only write flows (including apply_patch), this could allow writes to resolve outside the configured workspace/sandbox boundary.

The fix resolves symlink targets through existing ancestors and fails closed when canonical resolution escapes the configured boundary.

Impact

• Boundary-confined write operations could be redirected outside the configured workspace/sandbox root.
• Primary impact is integrity of host-side files reachable from that path resolution.

Fix Commit(s)

• 4fd29a35bb85a1898ebff518364c467058b50e14

Release Process Note

patched_versions is pre-set to the planned next release (2026.2.26) so once npm 2026.2.26 is published, the advisory can be published without further field edits.

Thanks @tdjackey for reporting.
