Xxyopen novel through 3.5.0 contains a weak password hashing vulnerability that allows attackers to recover plaintext passwords because UserServiceImpl.register() stores unsalted MD5 digests in user_info.password. Attackers who obtain the password column through a database leak or backup exposure can crack hashes with precomputed tables or GPU brute force and reuse credentials.
