How to Fix CVE-2026-26324

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: 2026.2.14 
npm install openclaw@2026.2.14
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-2026-26324, 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 2026.2.14), 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 OpenClaw's SSRF protection could be bypassed using full-form IPv4-mapped IPv6 literals such as `0:0:0:0:0:ffff:7f00:1` (which is `127.0.0.1`). This could allow requests that should be blocked (loopback / private network / link-local metadata) to pass the SSRF guard. - Vulnerable component: SSRF guard (`src/infra/net/ssrf.ts`) - Issue type: SSRF protection bypass ### Affected Packages / Versions - Package: `openclaw` (npm) - Vulnerable: `<= 2026.2.13` - Patched: `>= 2026.2.14` (planned next release) ### Details The SSRF guard's IP classification did not consistently detect private IPv4 addresses when they were embedded in IPv6 using full-form IPv4-mapped IPv6 notation. As a result, inputs like `0:0:0:0:0:ffff:7f00:1` could bypass loopback/private network blocking. ### Fix Commit(s) - `c0c0e0f9aecb913e738742f73e091f2f72d39a19` ### Release Process Note This advisory is kept in draft state with the patched version set to the planned next release. Once `openclaw@2026.2.14` is published to npm, the only remaining step should be to publish this advisory. Thanks @yueyueL for reporting.
