CVE-2026-49948

Estado: AplazadaAlta (8.6)—

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.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).

🎯 Técnicas ATT&CK

Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.

Mem0 requiere PR:L (API key autenticada) en red remota sin validación de rol. Impactos: acceso duradero con credencial válida (T1078), modificación persistente de configuración LLM (T1556), y potencial manipulación de datos en tránsito (T1565.001).

Inferido por nuestro agente de análisis a partir de la descripción oficial, el vector CVSS y la CWE, y comprobado por un supervisor. Puede contener errores.

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."
