CVE-2026-92873

Estado: Pendiente de análisisMedia (6.9)—

Pgpool-II contains an incorrect implementation of an authentication algorithm, which may allow an unauthenticated attacker to promote an arbitrary watchdog node to the leader node.

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.

Vulnerabilidad de autenticación en Pgpool-II accesible remotamente sin autenticación (AV:N/PR:N). Permite promoción no autorizada a nodo líder (escalada de privilegios en el sistema distribuido), permitiendo control administrativo y potencial manipulación de configuración.

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.
