CVE-2025-27451
This allows an attacker to guess usernames until they find an existing one.
MEDIUM 5.3EPSS 0.43%
Does this matter?
Lower severity and a low EPSS score (0.43%). Track it; it rarely justifies an emergency change on its own.
Description
For failed login attempts, the application returns different error messages depending on whether the login failed due to an incorrect password or a non-existing username. This allows an attacker to guess usernames until they find an existing one.
