Description

OpenClaw is a personal AI assistant. Versions 2026.2.13 and below allow the optional @openclaw/voice-call plugin Telnyx webhook handler to accept unsigned inbound webhook requests when telnyx.publicKey is not configured, enabling unauthenticated callers to forge Telnyx events. Telnyx webhooks are expected to be authenticated via Ed25519 signature verification. In affected versions, TelnyxProvider.verifyWebhook() could effectively fail open when no Telnyx public key was configured, allowing arbitrary HTTP POST requests to the voice-call webhook endpoint to be treated as legitimate Telnyx events. This only impacts deployments where the Voice Call plugin is installed, enabled, and the webhook endpoint is reachable from the attacker (for example, publicly exposed via a tunnel/proxy). The issue has been fixed in version 2026.2.14.
