OpenClaw has Missing Webhook Authentication in Telnyx Provider Allowing Unauthenticated Requests

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.

OpenClaw 访问控制错误漏洞

OpenClaw是openclaw开源的一个智能人工助理。 OpenClaw 2026.2.13及之前版本存在访问控制错误漏洞，该漏洞源于当telnyx.publicKey未配置时，@openclaw/voice-call插件Telnyx webhook处理程序接受未签名的入站webhook请求，可能导致未经验证的调用者伪造Telnyx事件。
