📋 Description
CFNext before 3.1.0 contains a weak cryptographic derivation vulnerability that allows subscription link holders to recover the admin password because the subscription UUID is an MD5 of the password with a fixed public salt. Attackers can brute-force the password offline without rate limiting, log into the admin panel, and read stored Trojan, Clash, Telegram and Cloudflare API secrets.
