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.

Technical Summary
PraisonAI, a multi-agent teams system by MervinPraison, has a vulnerability (CVE-2026-40116) in its call module's /media-stream WebSocket endpoint. Before version 4.5.128, this endpoint accepts connections from any client without authentication or Twilio signature validation. Each connection establishes an authenticated session to OpenAI's Realtime API using the server's API key. There are no restrictions on the number of concurrent connections, message rate, or message size, enabling an unauthenticated attacker to exhaust server resources and drain the victim's OpenAI API credits. The issue is addressed in PraisonAI version 4.5.128.
Potential Impact
An unauthenticated attacker can open unlimited WebSocket connections to the vulnerable endpoint, causing resource exhaustion on the server and depletion of OpenAI API credits associated with the server's API key. This results in denial of service conditions and financial impact due to API credit consumption. There is no direct confidentiality or integrity impact reported.
Mitigation Recommendations
This vulnerability is fixed in PraisonAI version 4.5.128. Users should upgrade to version 4.5.128 or later to remediate the issue. Patch status is not explicitly confirmed beyond the fix version, so verify with the vendor advisory for current remediation guidance.
