CVE-2026-55533: CWE-287: Improper Authentication in MervinPraison PraisonAI
Description
PraisonAI versions prior to 4.6.58 have an improper authentication vulnerability where the create_auth_middleware() function allows unauthenticated requests if the API key or JWT secret is missing. This enables an externally accessible Recipe server to accept unauthenticated POST requests to /v1/recipes/run despite authentication being enabled. The issue is resolved in version 4.6.58.

Technical Analysis
CVE-2026-55533 describes an improper authentication vulnerability (CWE-287) in MervinPraison's PraisonAI multi-agent teams system. Before version 4.6.58, the create_auth_middleware() function fails to enforce authentication properly when auth=api-key is used without the PRAISONAI_API_KEY or when JWT authentication lacks the PRAISONAI_JWT_SECRET. Consequently, an externally bound Recipe server can accept unauthenticated POST requests to the /v1/recipes/run endpoint, bypassing intended authentication controls. The vulnerability is fixed in version 4.6.58.
Potential Impact
An attacker can send unauthenticated POST requests to the /v1/recipes/run endpoint on an externally accessible Recipe server, potentially causing unauthorized actions despite authentication being enabled. The CVSS score of 8.2 indicates high severity with low attack complexity, no privileges required, no user interaction, and impacts confidentiality and integrity but not availability.
Mitigation Recommendations
Upgrade PraisonAI to version 4.6.58 or later, where this authentication bypass vulnerability is fixed. No other mitigation guidance is provided. Patch status is confirmed by the vendor stating the issue is fixed in 4.6.58.
