CVE-2026-65895

Grav API Plugin versions before 1.0.10 fail to restrict write access to security-critical plugin configuration scopes, allowing authenticated users with api.config.write privilege to modify rate limiting and CORS settings. Attackers can disable rate limiting site-wide to enable credential brute-forcing attacks and reconfigure CORS policies to include attacker-controlled origins with credentials enabled.

Summary		(es) Las versiones del plugin Grav API anteriores a la 1.0.10 no restringen el acceso de escritura a ámbitos de configuración del plugin críticos para la seguridad, lo que permite a usuarios autenticados con privilegio api.config.write modificar la limitación de velocidad y la configuración de CORS. Los atacantes pueden deshabilitar la limitación de velocidad en todo el sitio para habilitar ataques de fuerza bruta de credenciales y reconfigurar las políticas de CORS para incluir orígenes controlados por el atacante con credenciales habilitadas.
