  "details": "### Summary\nA path confinement bypass in OpenClaw ZIP extraction allowed writes outside the intended destination when a pre-existing symlink was present under the extraction root.\n\n### Affected Packages / Versions\n- Package: `openclaw` (npm)\n- Latest published npm version at triage time: `2026.2.21-2`\n- Affected versions: `\u003c= 2026.2.21-2`\n- Planned patched version for next release: `2026.2.22`\n\n### Technical Details\nThe vulnerable path was in `src/infra/archive.ts` ZIP extraction logic. Output-path checks were lexical, but writes could still traverse an existing symlink in destination path segments.\n\nThe fix blocks this by:\n- rejecting symlink traversal in destination path segments,\n- validating resolved destination paths remain inside the extraction root,\n- using no-follow file opens for ZIP output writes where supported,\n- adding a regression test for pre-seeded destination symlink traversal.\n\n### Impact\n- Type: Arbitrary file write outside extraction root via symlink traversal during ZIP extraction.\n- Preconditions: attacker-controlled archive extraction plus pre-existing symlink in destination path.\n\n### Fix Commit(s)\n- 4b226b74f5fd3b106a83a6347fd404172e2fd246\n\n### Release Process Note\nPatched version is pre-set to the planned next release (`2026.2.22`).\nOnce npm release `2026.2.22` is published, the advisory can be published without further field edits.\n\nOpenClaw thanks @tdjackey for reporting.",
