Estado: AnalizadaAlta (8.3)—

PhpSpreadsheet is a PHP library for reading and writing spreadsheet files. Versions prior to 3.7.0, 2.3.5, 2.1.6, and 1.29.7 are vulnerable to unauthorized reflected cross-site scripting in the `Accounting.php` file. Using the `/vendor/phpoffice/phpspreadsheet/samples/Wizards/NumberFormat/Accounting.php` script, an attacker can perform a cross-site scripting attack. Versions 3.7.0, 2.3.5, 2.1.6, and 1.29.7 contain a patch for the issue.

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.

XSS reflejado en script PHP accesible (Accounting.php); UI:A confirma interacción del usuario; CWE-79 es XSS; el atacante ejecuta JavaScript en navegador (T1059.007).

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.
