Summary

OpenClaw optional voice-call plugin: webhook verification may be bypassed behind certain proxy configurations

Details

Affected Packages / Versions

This issue affects the optional voice-call plugin only. It is not enabled by default; it only applies to installations where the plugin is installed and enabled.

Package: @openclaw/voice-call
Vulnerable versions: < 2026.2.3
Patched versions: >= 2026.2.3

Legacy package name (if you are still using it):

Package: @clawdbot/voice-call
Vulnerable versions: <= 2026.1.24
Patched versions: none published under this package name; migrate to @openclaw/voice-call

Summary

In certain reverse-proxy / forwarding setups, webhook verification can be bypassed if untrusted forwarded headers are accepted.

Impact

An external party may be able to send voice-call webhook requests that are accepted as valid, which can result in spoofed webhook events being processed.

Root Cause

Some deployments implicitly trusted forwarded headers (for example Forwarded / X-Forwarded-*) when determining request properties used during webhook verification. If those headers are not overwritten by a trusted proxy, a client can supply them directly and influence verification.

Resolution

Ignore forwarded headers by default unless explicitly trusted and allowlisted in configuration. Keep any loopback-only development bypass restricted to local development only. Upgrade to a patched version.

If you cannot upgrade immediately, strip Forwarded and X-Forwarded-* headers at the edge so clients cannot supply them directly.

CVE-2026-28465 (GCVE-0-2026-28465)

Vulnerability from cvelistv5 – Published: 2026-03-05 21:59 – Updated: 2026-09-17 17:54

Title

OpenClaw voice-call < 2026.2.3 - Webhook Verification Bypass via Forwarded Headers

Summary

OpenClaw's voice-call plugin versions before 2026.2.3 contain an improper authentication vulnerability in webhook verification that allows remote attackers to bypass verification by supplying untrusted forwarded headers. Attackers can spoof webhook events by manipulating Forwarded or X-Forwarded-* headers in reverse-proxy configurations that implicitly trust these headers.
