Estado: Pendiente de análisisAlta (8.8)—

A lack of authorization validation in version 1.0.0 or later of the ChromaDB Rust 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.

Acceso remoto autenticado (PR:L) sin interacción (UI:N) permite leer, escribir y eliminar datos en colecciones ajenas; T1210 por privilegios previos requeridos; impactos: lectura de datos (VC:H), manipulación (VI:H) e acceso a cuenta ajena via autorización.

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.
