# GHSA-gcj7-r3hg-m7w6: OpenClaw's voice-call Twilio replay dedupe now bound to authenticated webhook identity

> Attackers can bypass replay detection in OpenClaw's Twilio webhook by mutating unsigned headers, allowing replayed events to be processed as fresh.

- **Severity:** Not scored
- **Exploited in the wild:** Not known
- **Login needed:** Not needed
- **Attackable:** Over the internet

## What is GHSA-gcj7-r3hg-m7w6?

GHSA-gcj7-r3hg-m7w6 is a vulnerability in openclaw, published on 3 Mar 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

### Summary
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`: commit `1aadf26f9acc399affabd859937a09468a9c5cb4`
- Planned patched npm version: `2026.2.26`

### 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.

### 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.

### Fix Commit(s)
- `1aadf26f9acc399affabd859937a09468a9c5cb4`

### 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.

Affected packages and fixed versions:
- openclaw (npm): affected all versions; fixed in 2026.2.26
- openclaw (npm): affected all versions; fixed in 2026.2.26

Task:
1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.
2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.
3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.
4. Run the tests and summarise what changed and why.
5. If nothing in the project is affected, say so and change nothing.
