• CVE-2026-32029: 0.20% estimated exploitation activity in the next 30 days; percentile 9.47 (FIRST EPSS, 2026-11-03). This is a model estimate, not proof of exploitation or customer exposure.

As published by the source; long descriptions are shortened.

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 patchedversions is pre-set to the planned next release (2026.2.21). After npm release is out, publish this advisory. OpenClaw thanks…

# Patch Next advisory brief: CVE-2026-32029

Advisory: OpenClaw improperly parses X-Forwarded-For behind trusted proxies allows client IP spoofing in security decisions
IDs: CVE-2026-32029, GHSA-2rgf-hm63-5qph
Record: https://patchnext.com/advisories/cve-2026-32029 (revision 3, source checked 26 Oct 2026, 12:46 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Medium (CVSS 6.3)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: openclaw 2026.2.21. A vendor fix does not mean a deployment is fixed.

## Affected components
- npm openclaw: affected <= 2026.2.19-2; fixed in 2026.2.21

## Suggested inspection (read-only)
- `npm ls openclaw --all`: lists every installed copy and version, including transitive ones. Run in the project root after `npm ci`.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on openclaw.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.
