Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Admidio versions before 5.0.7 are vulnerable to cross-site request forgery when changing role membership start and end dates. The save_membership action does not validate the CSRF token. An attacker who gets a logged-in role leader to visit a crafted external page can silently alter membership dates for members of roles that leader manages, including ending their membership. Upgrade to Admidio 5.0.7 or later.
