CVE-2025-6386 Information

Description

The parisneo/lollms repository is affected by a timing attack vulnerability in the authenticate_user function within the lollms_authentication.py file. This vulnerability allows attackers to enumerate valid usernames and guess passwords incrementally by analyzing response time differences. The affected version is the latest and the issue is resolved in version 20.1. The vulnerability arises from the use of Python’s default string equality operator for password comparison which compares characters sequentially and exits on the first mismatch leading to variable response times based on the number of matching initial characters.
