• CVE-2026-32039: 0.20% estimated exploitation activity in the next 30 days; percentile 9.49 (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 channels..groups..toolsBySender could match a privileged sender policy using a colliding mutable identity value (for example senderName or senderUsername) when deployments used untyped keys. The fix introduces explicit typed sender keys (id:, e164:, username:, name:), keeps legacy untyped keys on a deprecated ID-only path, and adds regression coverage to prevent cross-identifier collisions. Affected Packages / Versions - Package: npm openclaw - Affected versions: <= 2026.2.21-2 - Latest published npm version at triage time (February 22, 2026): 2026.2.21-2 - Patched version (planned next release): 2026.2.22 Impact This is a sender-authorization bypass in group tool policy matching for deployments that use toolsBySender with untyped keys. Under those conditions, an attacker could inherit stronger tool permissions intended for another sender if they can force an identifier collision.

# Patch Next advisory brief: CVE-2026-32039

Advisory: OpenClaw's typed sender-key matching for toolsBySender prevents identity-collision policy bypass
IDs: CVE-2026-32039, GHSA-wpph-cjgr-7c39
Record: https://patchnext.com/advisories/cve-2026-32039 (revision 3, source checked 26 Oct 2026, 12:47 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Medium (CVSS 6.0)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: openclaw 2026.2.22. A vendor fix does not mean a deployment is fixed.

## Affected components
- npm openclaw: affected < 2026.2.22; fixed in 2026.2.22

## 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.
