CVE-2023-1549

Name of the Vulnerable Software and Affected Versions Ad Inserter WordPress plugin versions prior to 2.7.27

Description The issue allows high privilege users, such as admins, to perform PHP Object Injection when a suitable gadget is present. This is due to the plugin unserializing user input provided via the settings.
