How to Fix CVE-2026-32029

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: 2026.2.21
npm install openclaw@2026.2.21
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-2026-32029, 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 2026.2.21), 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-807: Reliance on Untrusted Inputs in a Security Decision, where the product uses a protection mechanism that relies on the existence or values of an input, but the input can be modified by an untrusted actor in a way that bypasses the protection mechanism. 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 used left-most `X-Forwarded-For` values when requests came from configured trusted proxies. In proxy chains that append/preserve header values, this could let attacker-controlled header content influence security decisions tied to client IP. ### Affected Packages / Versions - Package: `openclaw` (npm) - Affected: `<= 2026.2.19-2` - Patched: `2026.2.21` (planned next release) ### Impact Possible client-IP spoofing in security-sensitive paths (for example auth rate-limit identity and local/private classification) for deployments behind trusted proxies with non-recommended forwarding behavior. ### Scope Note OpenClaw docs recommend reverse proxies overwrite (not append/preserve) inbound forwarding headers. This condition reduces severity. ### Fix Commit(s) - `07039dc089e51589a213ec0d16f8d6f2cd871fa1` - `8877bfd11ec7760b115b2d0d7500a45da2749747` ### Release Process Note `patched_versions` is pre-set to the planned next release (`2026.2.21`). After npm release is out, publish this advisory. OpenClaw thanks @AnthonyDiSanti for reporting.
