CVE-2026-57132: CWE-287: Improper Authentication in MervinPraison PraisonAI
PraisonAI is a multi-agent teams system. Prior to 4.6.62, setting PRAISONAI_CALL_AUTH to disabled makes verify_token accept requests to /api/v1/agents/{id}/invoke without CALL_SERVER_TOKEN authentication. Deployments that use the application's advertised opt-out can expose registered agents and their connected tools or private context to unauthenticated invocation. The vulnerability is fixed in 4.6.62.
AI Analysis
Technical Summary
CVE-2026-57132 describes an improper authentication vulnerability (CWE-287) in MervinPraison's PraisonAI multi-agent teams system. When the configuration PRAISONAI_CALL_AUTH is set to disabled in versions before 4.6.62, the verify_token function does not require CALL_SERVER_TOKEN authentication for requests to the /api/v1/agents/{id}/invoke endpoint. This allows unauthenticated invocation of registered agents, potentially exposing sensitive agent data and connected tools. The vulnerability is resolved in version 4.6.62.
Potential Impact
An attacker can invoke registered agents without authentication, potentially exposing sensitive agent information and private context. The CVSS score of 8.2 (high) reflects the network attack vector, low attack complexity, no privileges or user interaction required, with high confidentiality impact and limited integrity impact. Availability is not affected.
Mitigation Recommendations
Upgrade PraisonAI to version 4.6.62 or later, where this vulnerability is fixed. Until then, avoid disabling PRAISONAI_CALL_AUTH to prevent unauthenticated access. No other mitigations are specified.
