Published 13 Oct 2026 · NVD status: Received · AI triage by gemini-3.8-flash

5.9Medium

Attack vector: Network
Complexity: High
Privileges needed: None
User interaction: None
Impact: High impact on confidentiality
Weakness: CWE-916

Impact

Attackers can reverse stored password hashes to plaintext using rainbow tables or brute force if they obtain a database leak or backup. This allows credential reuse across accounts.

Root cause

The registration handler computes unsalted MD5 hashes for user passwords before storing them in the database.

Affected systems

Xxyopen novel through 3.5.0

Fix & remediation

Upgrade to a commit incorporating pull request #53 / commit fa82ce7e426a5b29db469b8f13d2e29fc1260871 or a post-3.5.0 release; as an interim measure, restrict direct access and backup exposures to the database containing the user_info table.

shell

$ git pull origin main

NVD description

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.
