GHSA-WV94-5QCP-6M36 PraisonAI MCP HTTP server has unauthenticated unbounded session accumulation (memory exhaustion; session TTL never enforced)

Summary The PraisonAI MCP HTTP-stream server creates a new in-memory session on every initialize request and never removes it. The cleanup routine that would expire sessions cleanupsessions is defined but never called anywhere in the codebase, and the configured session TTL is never enforced. The...

CVE-2026-55531 PraisonAI: Unauthenticated unbounded session accumulation in the PraisonAI MCP HTTP server (memory exhaustion; session TTL never enforced)

PraisonAI is a multi-agent teams system. Prior to praisonai 4.6.58, the MCP HTTP Stream mcppost handler creates a new sessions entry for every initialize request but does not call cleanupsessions or enforce a maximum. An unauthenticated caller can exhaust memory. The fix invokes cleanup and limit...

CVE-2026-55529

PraisonAI (a multi-agent teams system) has an origin validation bypass in its MCP HTTP Stream transport. The _validate_origin method uses request_origin.startswith(allowed), so an attacker-controlled origin like http://localhost.evil.example matches the http://localhost allowlist entry via prefix...
