CVE-2025-2539
The File Away plugin for WordPress is vulnerable to unauthorized access of data due to a missing capability check on the ajax() function in all versions up to, and including, 3.9.9.0.1. This makes it possible for unauthenticated attackers, leveraging the use of a reversible weak algorithm, to read the contents of arbitrary files on the server, which can contain sensitive information.
CVSS
- Versión: 3.1
- Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N
- Puntuación base: 7.5
Probabilidad de explotación (EPSS)
- Probabilidad de explotación en los próximos 30 días: 1.65%
- Percentil entre todas las CVEs puntuadas: 76
- 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).
