Estado: ModificadaAlta (8.8)—

A lack of authorization validation in version 0.4.17 or later of the ChromaDB Python project allows any authenticated users to arbitrarily read, write, update, or delete data in any tenant's collection regardless of which tenant they belong to.

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.

ChromaDB carece de validación de autorización (CWE-639), permitiendo a usuarios autenticados (PR:L) leer/escribir/eliminar datos en cualquier tenant. Explotación remota con privilegios mínimos. Impactos: lectura de datos sensibles (T1005), modificación de datos en colecciones (T1565.001), riesgo de
