GHSA-xwjm-j929-xq7c OpenClaw has a Path Traversal in Browser Download Functionality

• npm openclaw: >= 2026.1.12, < 2026.2.13 → fixed in 2026.2.13

Summary OpenClaw browser download helpers accepted an unsanitized output path. When invoked via the browser control gateway routes, this allowed path traversal to write downloads outside the intended OpenClaw temp downloads directory. This issue is not exposed via the AI agent tool schema (no `download` action). Exploitation requires authenticated CLI access or an authenticated gateway RPC token. Affected Packages / Versions • Package: `openclaw` (npm) • Affected: >=2026.1.12, =2026.2.13 Details Affected code: `src/browser/pw-tools-core.downloads.ts` (`waitForDownloadViaPlaywright`, `downloadViaPlaywright`). Fixed entrypoints (as of 2026.2.13): • Gateway browser control routes `/wait/download` and `/download` now restrict `path` to `DEFAULT_DOWNLOAD_DIR` via `resolvePathWithinRoot`. Fix Commit(s) • 7f0489e4731c8d965d78d6eac4a60312e46a9426 Mitigation Upgrade to `openclaw` >=2026.2.13. Thanks @locus-x64 for reporting.
