CVE-2026-7311

Estado: AplazadaAlta (8.1)—

The TinyPNG – JPEG, PNG & WebP image compression plugin for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation in the delete_converted_image_size function in all versions up to, and including, 3.6.13. This makes it possible for authenticated attackers, with author-level access and above, to delete arbitrary files on the server, which can easily lead to remote code execution when the right file is deleted (such as wp-config.php). An attacker can exploit this by injecting an arbitrary server file path into the 'convert.path' field of the 'tiny_compress_images' post meta on an attachment they own, then triggering attachment deletion to invoke the vulnerable code path.

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.

Acceso remoto autenticado (PR:L) en WordPress permite manipular metadatos de adjuntos e inyectar rutas arbitrarias. Impactos: eliminación destructiva de archivos (T1485) e implícitamente RCE al borrar wp-config.php (T1059).

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.
