CVE-2026-57118

PraisonAI AgentTeam.launch() exposes unauthenticated remote agent invocation endpoints Summary PraisonAI's documented Python AgentTeam.launch() / Agents.launch() HTTP server starts externally reachable agent invocation endpoints without any authentication enforcement. The current implementation registers GET /{path}/list, POST /{path}, and POST /{path}/{agent_id} routes. The POST routes directly call agent.chat(...). Requests with no Authorization header are accepted, and requests with an obviously wrong bearer token are also accepted. The default Python API bind host for Agents.launch() is 0.0.0.0, and official documentation shows host="0.0.0.0" for remote access. This is a sibling/incomplete-fix variant of PraisonAI's prior unauthenticated API server and call server advisory family. Nearby server surfaces were hardened to require tokens, fail closed, or bind locally by default, but the AgentTeam.launch() FastAPI path still exposes unauthenticated agent execution on current upstream main and the latest release. This report is scoped to the Python AgentTeam.launch() / Agents.launch() route-registration path. It does not require adjudicating whether the separate praisonai serve agents --api-key CLI path is correctly enforced.
