CVE-2026-49948
Mem0 0.2.8 Missing Authorization via POST /configure Endpoint
Description
Mem0 versions through 0.2.8, fixed in commit ae7f406, contain a missing authorization vulnerability in the self-hosted server component where the POST /configure endpoint modifies global LLM provider and embedder configuration but only verifies authentication via JWT or X-API-Key without validating the caller's role. Any authenticated user holding a distributed API key can redirect all LLM and embedder traffic to an attacker-controlled server, with the malicious configuration persisted to PostgreSQL and surviving server restarts to affect all users and API keys on the instance.

Action Type Old Value New Value Added Translation Title: Mem0 de mem0ai, Description: Las versiones de Mem0 hasta la 0.2.8, corregidas en el commit ae7f406, contienen una vulnerabilidad de autorización faltante en el componente de servidor autoalojado donde el endpoint POST /configure modifica la configuración global del proveedor de LLM y del incrustador, pero solo verifica la autenticación a través de JWT o X-API-Key sin validar el rol del llamador. Cualquier usuario autenticado que posea una clave API distribuida puede redirigir todo el tráfico de LLM y del incrustador a un servidor controlado por un atacante, con la configuración maliciosa persistida en PostgreSQL y sobreviviendo a los reinicios del servidor para afectar a todos los usuarios y claves API en la instancia. -
