How to Fix CVE-2026-43526

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: 2026.4.12 
npm install openclaw@2026.4.12
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-2026-43526, 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 2026.4.12), 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 QQBot reply media URL handling could trigger SSRF and re-upload fetched bytes. ## Affected Packages / Versions - Package: `openclaw` - Ecosystem: npm - Affected versions: `< 2026.4.12` - Patched versions: `>= 2026.4.12` ## Impact QQBot reply media URLs could be treated as trusted media sources, allowing SSRF fetches whose returned bytes were then re-uploaded through the channel. ## Technical Details The fix routes QQBot remote media fetches through SSRF-guarded media fetching and explicit URL allowlist policy. ## Fix The issue was fixed in #63495 and #65788. The first stable tag containing the fix is `v2026.4.12`, and `openclaw@2026.4.14` includes the fix. ## Fix Commit(s) - `08ae021d1f4f02e0ca5fd8a3b9659291c1ecf95a` - `ddb7a8dd80b8d5dd04aafa44ce7a4354b568bb2d` - PR: #63495, #65788 ## Release Process Note Users should upgrade to `openclaw` 2026.4.12 or newer. The latest npm release, `2026.4.14`, already includes the fix. ## Credits Thanks to @threalwinky for reporting this issue.
