What fixes it

No source in this snapshot names a fixed version. The vendor advisories under References are the place to check.

Description

When Gitea's web installer is reachable against a database that already contains users, such as after INSTALL_LOCK has been reset to false, submitting the install form with an administrator username matching an existing account issued an authenticated session for that account without verifying its password. If the account is an administrator, the session grants full administrative access, including changing the account's password. Databases with a single user also did not require the reinstall confirmation.
