OpenClaw's voice-call Twilio webhook replay could bypass manager dedupe because normalized event IDs were randomized per parse

CVE-2026-32053GHSA-vqx8-9xxw-f2m7

What to do

Vendor fix available. Upgrade each affected package to the fixed version on its release line (openclaw 2026.2.23), redeploy, then verify what is actually installed.

This page has no inventory attached, so it cannot say whether you are affected. A vendor fix is not proof that your deployment is fixed.

Source description

As published by the source; long descriptions are shortened.

Impact Twilio webhook replay events could bypass voice-call manager dedupe because normalized event IDs were randomized per parse. A replayed event could be treated as new and trigger duplicate or stale call-state transitions. Affected Packages / Versions - Package: openclaw (npm) - Vulnerable versions: <= 2026.2.22-2 - Patched version (released): = 2026.2.23 Remediation The fix preserves provider event IDs through normalization, adds bounded replay dedupe in webhook security validation, and enforces per-call turn-token checks on call-state transitions. Fix Commit(s) - 1d28da55a5d0ff409e34999e0961157e9db0a2ab Release Process Note patchedversions is pre-set to the released version (2026.2.23) This advisory now reflects released fix version 2026.2.23.2.23. OpenClaw thanks @jiseoung for reporting.

# Patch Next advisory brief: CVE-2026-32053

Advisory: OpenClaw's voice-call Twilio webhook replay could bypass manager dedupe because normalized event IDs were randomized per parse
IDs: CVE-2026-32053, GHSA-vqx8-9xxw-f2m7
Record: https://patchnext.com/advisories/cve-2026-32053 (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 6.9)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: openclaw 2026.2.23. A vendor fix does not mean a deployment is fixed.

## Affected components
- npm openclaw: affected < 2026.2.23; fixed in 2026.2.23

## 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.

## Sources
- Verified: https://osv.dev/vulnerability/GHSA-vqx8-9xxw-f2m7 (OSV record GHSA-vqx8-9xxw-f2m7 lists affected ranges: npm openclaw >=0 <2026.2.23 (fixed))
- Verified: https://github.com/advisories/GHSA-vqx8-9xxw-f2m7 (GitHub-reviewed advisory GHSA-vqx8-9xxw-f2m7 lists affected ranges: npm openclaw >=0 <2026.2.23)
