How to Fix CVE-2026-28462

To remediate this vulnerability, upgrade all affected Openclaw dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

openclaw fixed: 2026.2.13
npm install openclaw@2026.2.13
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release:

npm ls openclaw

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2026-28462, inspect your project dependencies using npm:

npm ls openclaw

Analyze the terminal output to locate any version of Openclaw in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2026.2.13), your application is affected.

Note: The npm ls openclaw command inspects dependencies declared in your package.json and lockfile; it does not perform automated runtime dynamic scanning.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal'), where the product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. In Openclaw, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

## Summary OpenClaw’s browser control API accepted user-supplied output paths for trace/download files without consistently constraining writes to OpenClaw-managed temporary directories. ## Impact If an attacker can access the browser control API, they could attempt to write trace/download output files outside intended temp roots, depending on process filesystem permissions. ## Affected versions `openclaw` `< 2026.2.13` ## Fixed versions `openclaw` `>= 2026.2.13` ## Remediation Upgrade to `2026.2.13` or later. ## What changed The fix constrains output paths for: - `POST /trace/stop` - `POST /wait/download` - `POST /download` All three now enforce OpenClaw temp-root boundaries and reject traversal/escape paths. ## Credits Thanks to Adnan Jakati (@jackhax) of Praetorian for responsible disclosure. Fix shipped in PR #15652 and merged to `main` on February 13, 2026 (`7f0489e4731c8d965d78d6eac4a60312e46a9426`). --- Fix commit 7f0489e4731c8d965d78d6eac4a60312e46a9426 confirmed on main and in v2026.2.14. Upgrade to `openclaw >= 2026.2.13`.
