Description
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`
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.
