How to Fix CVE-2026-32053

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: 2026.2.23 
npm install openclaw@2026.2.23
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-2026-32053, 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 2026.2.23), 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-294: Authentication Bypass by Capture-replay, where a capture-replay flaw exists when the design of the product makes it possible for a malicious user to sniff network traffic and bypass authentication by replaying it to the server in question to the same effect as the original message (or with minor changes). 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

## 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 `patched_versions` 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.
