How to Fix CVE-2026-32018

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: 2026.2.19 
npm install openclaw@2026.2.19
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-2026-32018, 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 2026.2.19), 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-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition'), where the product contains a concurrent code sequence that requires temporary, exclusive access to a shared resource, but a timing window exists in which the shared resource can be modified by another code sequence operating concurrently. 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

## Impact Concurrent `updateRegistry`/`removeRegistryEntry` operations for sandbox containers and browsers could lose updates or resurrect removed entries under race conditions. The registry writes were read-modify-write in a window with no locking and permissive fallback parsing, so concurrent registry updates could produce stale snapshots and overwrite each other. That desyncs sandbox state and can affect `sandbox list`, `sandbox prune`, and `sandbox recreate --all` behavior. ## Affected Packages / Versions - Package: `openclaw` (npm) - Affected versions: `<= 2026.2.17` - Patched versions: `2026.2.18` ## Fix Commit(s) - `cc29be8c9` OpenClaw thanks @kexinoh for reporting.
