CVE-2026-100372

Estado: AplazadaAlta (8.6)—

ClipBucket v5 before 5.5.3-#197 contains a path traversal vulnerability in the admin template editor that allows authenticated administrators to overwrite PHP files by supplying directory traversal sequences in the folder parameter. Attackers with manage_template_access permission can traverse outside the layout directory to modify executable PHP files and achieve remote code execution as the web server user.

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.

Requiere autenticación local (PR:H, admin autenticado). Escalada de privilegios mediante path traversal para sobrescribir archivos PHP y ejecutar código. CWE-22 confirma traversal; VC:H/VI:H/VA:H indica impacto crítico en confidencialidad, integridad y disponibilidad.

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.
