AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N

Name of the Vulnerable Software and Affected Versions Koel versions prior to 5.1.4

Description The issue lacks login throttling, lacks a password strength policy, and shows whether a failed login attempt had a valid username, which might make brute-force attacks easier.

Recommendations For versions prior to 5.1.4, update to version 5.1.4 or later to resolve the issue. As a temporary workaround, consider implementing a custom login throttling mechanism and enforcing a strong password policy to minimize the risk of exploitation. Restrict access to the login functionality to minimize the risk of brute-force attacks.
