CVE-2026-40116

PraisonAI's Unauthenticated WebSocket Endpoint Proxies to Paid OpenAI Realtime API Without Rate Limits

State: Published
Severity: 7.5 High
Published: Apr 9, 2026
Updated: Apr 14, 2026
Reserved: Apr 9, 2026

Description

PraisonAI is a multi-agent teams system. Prior to 4.5.128, the /media-stream WebSocket endpoint in PraisonAI's call module accepts connections from any client without authentication or Twilio signature validation. Each connection opens an authenticated session to OpenAI's Realtime API using the server's API key. There are no limits on concurrent connections, message rate, or message size, allowing an unauthenticated attacker to exhaust server resources and drain the victim's OpenAI API credits. This vulnerability is fixed in 4.5.128.
