CVE-2026-11832

Estado: AplazadaCrítica (9.1)—

Dancer2::Plugin::Auth::OAuth versions before 0.22 for Perl default to a predictable nonce.

The default nonce was generated using an MD5 hash of the epoch time, which is predictable.

CVSS

Versión: 3.1
Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N
Puntuación base: 9.1

Probabilidad de explotación (EPSS)

Probabilidad de explotación en los próximos 30 días: 0.33%
Percentil entre todas las CVEs puntuadas: 24
Fecha de la puntuación: 5/10/2026

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:3.1/AV:N/AC:L/PR:N/UI:N indica explotación remota sin privilegios (T1190). El nonce predecible permite suplantación de identidad OAuth, logrando acceso de cuenta (T1078) y posible manipulación de autenticación (T1556).

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.
