Unauthenticated Agent Enumeration and Invocation in PraisonAI AgentOS

IdentifiersCVE-2026-57116CWE-306

CVE-2026-57116 is an authentication flaw in PraisonAI AgentOS caused by an incomplete fix for a prior advisory. Exposed FastAPI routes handling agent discovery and chat invocation remain accessible without authentication, allowing remote unauthenticated clients to enumerate deployed agents and invoke them. The issue affects the security boundary around AgentOS and AgentApp by failing to consistently enforce bearer authentication on sensitive API endpoints. In reachable deployments, this permits unauthorized interaction with agent functionality and any downstream capabilities exposed through those agents.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

Successful exploitation allows an unauthenticated remote attacker to discover available agents and invoke them through the chat interface. Depending on how the deployed agents are configured, this can expose private context or memory, trigger integrated tools or external API actions, perform browser-driven operations, cause other unintended side effects, and consume model or API budget. In practice, the vulnerability can result in unauthorized agent control and misuse of connected capabilities in internet-exposed deployments.

Mitigation

If you can’t patch tonight, do this now.

Until a fixed release is deployed, do not expose AgentOS on reachable network interfaces. Restrict binding to localhost where possible, or place the service behind an authenticating reverse proxy that enforces bearer authentication before requests reach the application. Avoid non-loopback binds unless compensating access controls are in place, reduce network reachability to trusted administrators or systems only, and monitor for unauthorized access attempts against the affected API functionality.

Remediation

Patch, then assume compromise.

Upgrade PraisonAI to version 4.6.59 or later. Ensure the AgentOS and AgentApp security model enforces authentication by default, rejects unauthenticated and invalid bearer-token requests on sensitive API routes, defaults the bind host to localhost, and fails closed when configured for non-loopback exposure without authentication. Regression testing should verify that authentication is enforced on agent enumeration and invocation endpoints.
