CVE-2025-14202

Estado: AplazadaAlta (8.2)—

A vulnerability in the file upload at bookmark + asset rendering pipeline allows an attacker to upload a malicious SVG file with JavaScript content. When an authenticated admin user views the SVG file with embedded JavaScript code of shared bookmark, JavaScript executes in the admin’s browser, retrieves the CSRF token, and sends a request to change the admin's password resulting in a full account takeover.

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 via SVG malicioso en bookmark permite ejecutar JavaScript en navegador de admin autenticado. CWE-79 y ejecución de código + cambio de contraseña (T1098.002) = secuestro de cuenta.

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.
