Details
Summary
CVE-2023-2440 is a Cross-Site Request Forgery (CSRF) vulnerability affecting the UserPro plugin for WordPress. The flaw, present in versions up to 5.1.1, stems from the absence of nonce validation in the 'admin_page', 'userpro_verify_user', and 'verifyUnverifyAllUsers' functions. Consequently, unauthenticated attackers can manipulate the role of verified users, escalating their privileges to that of any user, such as an administrator, by forging a malicious request. Site administrators are potentially susceptible to this exploit if they unwittingly execute the attacker's request.
