CVE-2026-25235

Estado: AnalizadaAlta (8.2)—

PEAR is a framework and distribution system for reusable PHP components. Prior to version 1.33.0, predictable verification hashes may allow attackers to guess verification tokens and potentially verify election account requests without authorization. This issue has been patched in version 1.33.0.

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 indica acceso remoto (AV:N) sin privilegios ni interacción (PR:N, UI:N). CWE-337 (generación predecible) permite adivinar tokens de verificación para autorizar cuentas sin permiso (impacto de cuenta/credencial).

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.
