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

Payara Server Full versions 4.0.0 up to but not including 7.2026.6 are affected by a cross-site request forgery vulnerability in the Admin GUI. An attacker who can get a logged-in administrator to visit a crafted page can cause the admin REST session token to be sent to an attacker-controlled host, then reuse it to take full administrative control and deploy code. Upgrade to Payara Server Full 7.2026.6 or later.
