CVE-2026-3172

Estado: AplazadaAlta (8.1)—

Buffer overflow in parallel HNSW index build in pgvector 0.6.0 through 0.8.1 allows a database user to leak sensitive data from other relations or crash the database server.

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.

Buffer overflow remoto en servicio pgvector (AV:N, PR:L) permite fuga de datos sensibles (CWE-191, CWE-787) o DoS del servidor. Requiere autenticación, compatible con T1210.

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.
