PraisonAI is a multi-agent teams system. Prior to 4.5.115, the A2U (Agent-to-User) event stream server in PraisonAI exposes all agent activity without authentication. The create_a2u_routes() function registers the following endpoints with NO authentication checks: /a2u/info, /a2u/subscribe, /a2u/events/{stream_name}, /a2u/events/sub/{id}, and /a2u/health. This vulnerability is fixed in 4.5.115.

 https://cve.radiocsirt.org/vuln/ghsa-f292-66h9-fpmf GHSA-f292-66h9-fpmf — PraisonAI Has Unauthenticated SSE Event Stream that Exposes All Agent Activity in A2U Server 2026-10-14T23:56:55.390443+00:00

Affected: PyPI: praisonai

The A2U (Agent-to-User) event stream server in PraisonAI exposes all agent activity without authentication. This is a separate component from the gateway server fixed in CVE-2026-34952.

The create_a2u_routes() function registers the following endpoints with NO authentication checks: - GET /a2u/info — exposes server info and stream names - POST /a2u/subscribe — creates event stream subscription - GET /a2u/events/{stream_name} — streams ALL agent events - GET /a2u/events/sub/{id} — streams events for subscription - GET /a2u/health — health check

An unauthenticated attacker can: 1. POST /a2u/subscribe → receive subscription_id 2. GET /a2u/events/sub/{subscription_id} → receive live SSE stream of all agent events including responses, tool calls, and thinking

This exposes sensitive agent activity including responses, internal reasoning, and tool call arguments to any network attacker.
