CVE-2026-14676

Estado: ModificadaAlta (8.8)—

Heap buffer overflow in PostgreSQL pg_stat_statements allows the query author to execute arbitrary code as the operating system user running the database, via crafted queries containing array constants. Within major version 18, minor versions before PostgreSQL 18.6 are affected. Versions before PostgreSQL 18 are unaffected.

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.

Vector CVSS AV:N/AC:L/PR:L/UI:N indica acceso remoto con privilegios de base de datos. Heap buffer overflow permite ejecución arbitraria de código como usuario del SO. T1210 por servicios remotos con PR:L; impactos T1059 (ejecución de comandos) y T1068 (escalada a usuario del SO).

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.
