Security Advisory
CVE-2023-2546
CVE vulnerability detail — eXtreme Datacenter Security Operations
Description
The WP User Switch plugin for WordPress is vulnerable to authentication bypass in versions up to, and including, 1.0.2. This is due to incorrect authentication checking in the wpus_allow_user_to_admin_bar_menu function with the wpus_who_switch cookie value. This makes it possible for authenticated attackers, with subscriber-level permissions and above, to log in as any existing user on the site, such as an administrator, if they have access to the username.
