Estado: AplazadaAlta (8.8)—

phpMyFAQ before 4.1.3 contains an unauthenticated password reset vulnerability in the user password update API endpoint that allows attackers to change account passwords without token validation. Attackers can enumerate valid username and email pairs and force immediate password changes by sending PUT requests to the /api/index.php/user/password/update endpoint, causing account disruption and invalidating legitimate user credentials.

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.
