CVE-2026-36471

Estado: AplazadaMedia (5.8)—

Deserialization of Untrusted Data of the __post_data parameter in cn_parse_url() in CuteNews v.2.1.2 allows a remote attacker to inject arbitrary values into internal request variables (including __referer) via a crafted base64-encoded serialized PHP payload submitted as a POST parameter.

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.

CWE-502 (insecure deserialization) en parámetro POST con payload PHP serializado permite inyectar valores arbitrarios; requiere interacción (UI:R) para enviar payload crafted, típico de T1203. Impacto: ejecución de código PHP (T1059) y manipulación de variables internas como __referer (T1565.001).

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.
