How to Fix CVE-2026-44112

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: 2026.4.22 
npm install openclaw@2026.4.22
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-2026-44112, 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 2026.4.22), 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-367: Time-of-check Time-of-use (TOCTOU) Race Condition, where the product checks the state of a resource before using that resource, but the resource's state can change between the check and the use in a way that invalidates the results of the check. 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 OpenShell FS bridge writes stay pinned to the sandbox mount root ## Affected Packages / Versions - Package: openclaw (npm) - Affected versions: <= 2026.4.21 - Fixed version: 2026.4.22 ## Impact A time-of-check/time-of-use race around OpenShell sandbox filesystem writes could let a symlink swap redirect a write outside the intended local mount root. ## Fix OpenShell write paths now validate the canonical target against the mount root, reject unsafe symlink parents and symlink leaves for writes, and use root-scoped write helpers before syncing to the remote sandbox. ## Fix Commit(s) - 7be82d4fd1193bcb7e44ee38838f00bf924ffa76 ## Verification - The fix commit is contained in the public v2026.4.22 tag. - openclaw@2026.4.22 is published on npm and the compiled package contains the fix. - Focused regression coverage for this path passed before publication.
