CVE-2026-86437

Estado: AplazadaAlta (8.6)—

Lara Dashboard before 1.3.2 authorizes the POST /admin/settings/core-upgrades/upload endpoint with only the settings.edit permission, allowing non-Superadmin administrators to upload and extract arbitrary zip archives over the live application source code. Attackers can upload a malicious archive containing modified application files such as routes/web.php with embedded system commands, which execute as the web server user with access to environment secrets and database credentials.

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.

Vulnerabilidad de autorización débil en endpoint remoto que permite escalada lateral: administrador no-superadmin explota CWE-863 para subir archivos ZIP maliciosos sobre código fuente en vivo, ejecutando comandos del sistema y accediendo a secretos de entorno.

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.
