Description

Summary

In certain workspace-restricted configurations, OpenClaw could follow hardlink aliases inside the workspace that reference files outside the workspace boundary.

By default, tools.fs.workspaceOnly is off. This primarily affects deployments that intentionally enable workspace-only filesystem restrictions (and workspace-only apply_patch checks).

Impact

  • Confidentiality: out-of-workspace files could be read through in-workspace hardlink aliases.
  • Integrity: out-of-workspace files could be modified through in-workspace hardlink aliases.

Affected Packages / Versions

  • Package: openclaw (npm)
  • Latest published version at triage time: 2026.2.24
  • Affected range: <= 2026.2.24
  • Planned patched version: 2026.2.25

Fix Commit(s)

  • 04d91d0319b82fd4de91ed05e9fc5219ff2ab64e (main)

Remediation

OpenClaw now rejects hardlinked final-file aliases during workspace boundary validation for:

  • workspace-only path checks (read / write / edit)
  • workspace-only apply_patch read/write paths
  • sandbox mount-root path-safety checks

Regression tests were added for apply_patch, workspace fs tools, and sandbox fs bridge hardlink alias escapes.

OpenClaw thanks @tdjackey for reporting.
