Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Admidio, the open-source membership management software distributed as the Packagist package admidio/admidio, is vulnerable in versions before 5.0.10. The send_login mode of the registration module does not check the CSRF token, and it accepts GET requests. An attacker who can get a registration administrator to load a crafted page while logged in can reset the password of any chosen user without the admin's knowledge, locking that user out. The fix is to upgrade to version 5.0.10.
