CVE-2026-40116: CWE-770: Allocation of Resources Without Limits or Throttling in MervinPraison PraisonAI
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.
AI Analysis
Technical Summary
PraisonAI, a multi-agent teams system by MervinPraison, has a resource exhaustion vulnerability (CWE-770) in versions before 4.5.128. The /media-stream WebSocket endpoint allows unauthenticated clients to connect and open sessions to OpenAI's Realtime API using the server's API key without any throttling or limits on connections, message rate, or size. This can lead to denial of service by exhausting server resources and draining API credits. The vulnerability is addressed in version 4.5.128.
Potential Impact
An unauthenticated attacker can exploit this vulnerability to open unlimited WebSocket connections to the /media-stream endpoint, causing resource exhaustion on the server and depletion of the victim's OpenAI API credits. This results in denial of service conditions and financial impact due to API credit consumption. There is no confidentiality or integrity impact reported.
Mitigation Recommendations
Upgrade PraisonAI to version 4.5.128 or later, where this vulnerability is fixed. The fix includes authentication and Twilio signature validation on the /media-stream WebSocket endpoint and implements limits on concurrent connections, message rate, and message size to prevent resource exhaustion. No other mitigation is indicated.
