How to Fix CVE-2026-32019

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: 2026.2.22
npm install openclaw@2026.2.22
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-2026-32019, 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 2026.2.22), 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-918: Server-Side Request Forgery (SSRF), where the web server receives a url or similar request from an upstream component and retrieves the contents of this url, but it does not sufficiently ensure that the request is being sent to the expected destination. 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 `isPrivateIpv4()` in bundled SSRF guard code missed several IPv4 special-use/non-global ranges, so `web_fetch` could allow targets that should be blocked by SSRF policy. ### Affected Packages / Versions - Package: `openclaw` (npm) - Latest published affected version: `2026.2.21-2` (published 2026-02-21) - Structured vulnerable range: `<= 2026.2.21-2` - Planned patched version (pre-set): `>= 2026.2.22` ### Impact Low severity. Exploitation requires network reachability to the relevant special-use ranges and a request path that reaches `web_fetch` URL fetching. ### Technical Details Affected releases used narrow IPv4 private-range checks that omitted multiple RFC special-use/non-global ranges. This allowed requests such as `http://198.18.0.1/...` through SSRF validation in affected releases. Follow-up hardening consolidates local-host/tailnet range checks so gateway/browser/tailnet paths share one canonical IP classification flow. ### Fix Commit(s) - `71bd15bb4294d3d1b54386064d69cd0f5f731bd8` - `44dfbd23df453e51b71ef79a148c28c53e89168c` - `333fbb86347998526dd514290adfd5f727caa6d9` - `f14ebd743cfc73f667fae80af70043d0ab1f88bd` OpenClaw thanks @princeeismond-dot for reporting.
