Denial Of Service Praisonai

Description

PraisonAI is a multi-agent teams system. Prior to 4.5.128, the WSGI-based recipe registry server (server.py) reads the entire HTTP request body into memory based on the client-supplied Content-Length header with no upper bound. Combined with authentication being disabled by default (no token configured), any local process can send arbitrarily large POST requests to exhaust server memory and cause a denial of service. The Starlette-based server (serve.py) has RequestSizeLimitMiddleware with a 10MB limit, but the WSGI server lacks any equivalent protection. This vulnerability is fixed in 4.5.128.

Analysis

Memory exhaustion denial of service in PraisonAI's WSGI-based recipe registry server (server.py) affects versions prior to 4.5.128. The vulnerability allows unauthenticated local processes to send arbitrarily large POST requests by spoofing the Content-Length header, causing the server to allocate unbounded memory and crash. …
