CVE-2026-73195

Estado: AplazadaAlta (7.3)—

Improper Encoding or Escaping of Output vulnerability in Apache Syncope.

Authenticated users can store a spreadsheet formula payload in one of their own plain attributes. When such users are included in a CSV export and the generated CSV file is opened by a spreadsheet application, the formula may be executed.

This issue affects Apache Syncope: from 3.0.0-M0 through 3.0.16, from 4.0.0-M0 Through 4.0.7, from 4.1.0-M0 through 4.1.2.

Users are recommended to upgrade to version 4.0.8 / 4.1.3, which fix this 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.

CSV formula injection requiere interacción (abrir CSV en aplicación); UI:R confirma T1203. Ejecución de fórmulas/comandos (T1059) y lectura de datos del usuario autenticado (T1005) como impactos.

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.
