PYSEC-2026-474 PraisonAI Has Missing Authentication in WebSocket Gateway

Summary The PraisonAI Gateway server accepts WebSocket connections at /ws and serves agent topology at /info with no authentication. Any network client can connect, enumerate registered agents, and send arbitrary messages to agents and their tool sets. Details gateway/server.py:242 source -...

PYSEC-2026-473 PraisonAI has an incomplete fix for CVE-2026-34935 - OS Command Injection

Summary The fix for PraisonAI's MCP command handling does not add a command allowlist or argument validation to parsemcpcommand, allowing arbitrary executables like bash, python, or /bin/sh with inline code execution flags to pass through to subprocess execution. Affected Package - Ecosystem: PyP...

PYSEC-2026-468 PraisonAI Has Authentication Bypass via OAuthManager.validate_token()

Summary OAuthManager.validatetoken returns True for any token not found in its internal store, which is empty by default. Any HTTP request to the MCP server with an arbitrary Bearer token is treated as authenticated, granting full access to all registered tools and agent capabilities. Details...

PYSEC-2026-467 PraisonAI Browser Server allows unauthenticated WebSocket clients to hijack connected extension sessions

Summary praisonai browser start exposes the browser bridge on 0.0.0.0 by default, and its /ws endpoint accepts websocket clients that omit the Origin header entirely. An unauthenticated network client can connect as a fake controller, send startsession, cause the server to forward startautomation...

PYSEC-2026-470 PraisonAI Has Second-Order SQL Injection in `get_all_user_threads`

Summary The getalluserthreads function constructs raw SQL queries using f-strings with unescaped thread IDs fetched from the database. An attacker stores a malicious thread ID via updatethread. When the application loads the thread list, the injected payload executes and grants full database...
