An issue was discovered in weijiang1994 university-bbs (aka Blogin) in commit 9e06bab430bfc729f27b4284ba7570db3b11ce84 (2025-01-13). A weak verification code generation mechanism combined with missing rate limiting allows attackers to perform brute-force attacks on verification codes without authentication. Successful exploitation may result in account takeover via password reset or other authentication bypass methods.
