Summary
OpenClaw's voice-call Twilio replay dedupe now bound to authenticated webhook identity
The voice-call Twilio webhook path accepted replay/dedupe identity from unsigned request metadata (i-twilio-idempotency-token), enabling replayed signed requests to bypass replay detection and manager dedupe by mutating only that header.
Affected Packages / Versions
- Package:
openclaw(npm) - Affected versions:
<= 2026.2.25(latest published npm version at triage time) - Fixed on
main: commit1aadf26f9acc399affabd859937a09468a9c5cb4 - Planned patched npm version:
2026.2.26
Technical Details
The fix removes unsigned-header trust from Twilio replay/dedupe identity and binds replay/manager dedupe to authenticated request material. It also threads a verified request identity through provider parsing so dedupe uses verification-derived identity rather than mutable headers.

Release Process Note
patched_versions is pre-set to the planned next release (2026.2.26). After the npm release is published, this advisory can be published without additional version-field edits.
OpenClaw thanks @tdjackey for reporting.
Impact
Deployments using the optional voice-call Twilio webhook path could accept replayed webhook events as fresh events when an attacker had one valid signed request and changed only the unsigned idempotency header.
GHSA-GCJ7-R3HG-M7W6 has a CVSS score of 3.7 (Low). The vector is network-reachable, no privileges required, and no user interaction. A CVSS score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether this affects your application depends on whether the vulnerable code is present and reachable in your environment. A fixed version is available (2026.2.26); upgrading removes the vulnerable code path.

Kodem intelligence
Severity tells you how bad this could be in the worst case. It does not tell you whether you are exposed. Exploitability and impact are functions of runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A vulnerable package can sit in your dependency tree and never run.
Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter. Kodem's runtime-powered SCA identifies whether this CVE is reachable in your applications.

Frequently Asked Questions
- What is GHSA-GCJ7-R3HG-M7W6? GHSA-GCJ7-R3HG-M7W6 is a low-severity security vulnerability in openclaw (npm), affecting versions <= 2026.2.25. It is fixed in 2026.2.26.
- How severe is GHSA-GCJ7-R3HG-M7W6? GHSA-GCJ7-R3HG-M7W6 has a CVSS score of 3.7 (Low). This score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether it represents real risk in your environment depends on whether the vulnerable code is present and reachable.
- Which versions of openclaw are affected by GHSA-GCJ7-R3HG-M7W6? openclaw (npm) versions <= 2026.2.25 is affected.
- Is there a fix for GHSA-GCJ7-R3HG-M7W6? Yes. GHSA-GCJ7-R3HG-M7W6 is fixed in 2026.2.26. Upgrade to this version or later.
- Is GHSA-GCJ7-R3HG-M7W6 exploitable, and should I be worried? Whether GHSA-GCJ7-R3HG-M7W6 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

- What actually determines whether GHSA-GCJ7-R3HG-M7W6 is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
