Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Sulu (sulu/sulu) versions 2.5.0 before 2.5.10 reveal through the Admin Login form whether a given username or email exists, which allows account enumeration. The issue affects installations using the newer Symfony security system, and the source gives few details on other requirements. Upgrade to version 2.5.10, or as a workaround, make the authentication failure handler return the exception's message key instead of its full message.
