Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Kimai, the Packagist package kimai/kimai, is vulnerable in versions before 2.58.0. A password reset or admin-generated login link stays usable for up to two more logins within one hour after the user has already changed their password, so anyone who obtained the original link (for example through a mail scanner, shared inbox, browser history, or logs) can gain an authenticated session. Upgrade to version 2.58.0, which ties the login link signature to the password hash so the link expires once the password changes.
