bunkerweb is an Open-source and next-generation Web Application Firewall (WAF). 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.
