Administrator takeover via tokenless changeup request
Published Apr 4, 2026 · Updated Apr 4, 2026
Cross-site request forgery in sNews 1.7 allows remote attackers to change administrator credentials through a crafted HTML form. The changeup action accepts POSTed uname, pass1, and pass2 values and updates the logged-in administrator's username and password without a request token. An authenticated administrator must visit the attacker's page; a successful request replaces the credentials and grants administrative access.
