How to Fix CVE-2026-41355

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: 2026.3.28
npm install openclaw@2026.3.28
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-2026-41355, 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 2026.3.28), 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-829: Inclusion of Functionality from Untrusted Control Sphere, where the product imports, requires, or includes executable functionality (such as a library) from a source that is outside of the intended control sphere. 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 `mirror` mode can convert untrusted sandbox files into explicitly enabled workspace hooks and execute them on the host during gateway startup ## Current Maintainer Triage - Status: narrow - Normalized severity: medium - Assessment: Real on shipped <=2026.3.22 OpenShell mirror sync, but exploit needs mirror mode plus hooks enabled plus explicit hook opt-in plus restart, so high is overstated even though the direct fix shipped in v2026.3.28. ## Affected Packages / Versions - Package: `openclaw` (npm) - Latest published npm version: `2026.3.31` - Vulnerable version range: `<=2026.3.24` - Patched versions: `>= 2026.3.28` - First stable tag containing the fix: `v2026.3.28` ## Fix Commit(s) - `c02ee8a3a4cb390b23afdf21317aa8b2096854d1` — 2026-03-25T19:59:07Z ## Release Process Note - The fix is already present in released version `2026.3.28`. - This draft looks ready for final maintainer disposition or publication, not additional code-fix work.
