freeipa — security advisory
A flaw was found in FreeIPA. An unauthenticated remote attacker could exploit a DOM Cross-Site Scripting (XSS) vulnerability in the FreeIPA/IdM Web UI password reset page. By enticing a victim to click a specially crafted link and complete a password reset, the attacker could inject and execute arbitrary JavaScript code. This allows the attacker to perform actions within the victim's authenticated session, potentially leading to full administrative control if an IdM administrator is targeted.
