Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
vantage6 versions before 3.8.0 are vulnerable to an observable response discrepancy in login. The login error for a wrong username or password is the same, but a user account is temporarily blocked after repeated wrong passwords, so an attacker can still determine which usernames exist. Upgrade to vantage6 3.8.0 or later. The source lists no workaround.
