WordPress account enumeration
|wordpress-account-enumeration (31262)||Medium Risk|
WordPress could allow a remote attacker to determine valid usernames. WordPress returns different error messages depending on whether a valid username has been entered during a login attempt. Additionally, there is no restriction for the number of invalid login attempts to the application. An attacker could use this information to enumerate valid usernames and perform dictionary or brute force attacks to gain access to the application.
For Gentoo Linux:
