CVE-2026-3141

Estado: AplazadaCrítica (9.1)—

The FormGent plugin for WordPress is vulnerable to unauthorized arbitrary file deletion due to a missing capability check on the /wp-json/formgent/responses/attachments REST API endpoint in all versions up to, and including, 1.9.2 This is due to the REST API route being registered without any authentication middleware in routes/rest/api.php. This makes it possible for unauthenticated attackers to delete arbitrary files within the formgent uploads directory.

Additionally, on Linux servers where the wp-content/uploads/formgent directory does not yet exist (the default state after plugin installation), the path traversal protection can be bypassed, enabling deletion of arbitrary files including wp-config.php which can lead to complete site takeover via a fresh WordPress installation.

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.

REST API sin autenticación (AV:N, PR:N, UI:N) permite eliminación arbitraria de archivos incluido wp-config.php, comprometiendo la integridad y causando toma de control del sitio.

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.
