From 1.6.2 until 1.6.12, the BunkerWeb web UI BiscuitMiddleware authorization bypass list included the /cache/ URL prefix, so routes in src/ui/app/routes/cache.py protected only by @login_required, including POST /cache/delete, allowed low-privilege read-only reader accounts to permanently delete job cache files containing blacklist, greylist, DNSBL, CrowdSec, GeoIP, ModSecurity CRS, Let's Encrypt, ACME, and custom configuration data. This issue is fixed in version 1.6.12."

Desde la versión 1.6.2 hasta la 1.6.12, la lista de omisión de autorización de BiscuitMiddleware de la interfaz de usuario web de BunkerWeb incluía el prefijo de URL /cache/, por lo que las rutas en src/ui/app/routes/cache.py protegidas solo por @login_required, incluyendo POST /cache/delete, permitían a cuentas de lector de solo lectura con bajos privilegios eliminar permanentemente archivos de caché de trabajos que contenían datos de configuración de lista negra, lista gris, DNSBL, CrowdSec, GeoIP, ModSecurity CRS, Let’s Encrypt, ACME y personalizados. Este problema está solucionado en la versión 1.6.12."
