Nextcloud: Ratelimiting can be bypassed using IPv6 subnets

Nextcloud hardcodes IPv6 subnets to /128. End users get at least a /64 subnet more than the whole IPv4 address space!, most providers assign even larger subnets like /48. The subnet is used to block bruteforce attempts 3 and rate limiting 4. An attacker can easily generate random addresses from t...
