The Classified Listing – Classified ads & Business Directory Plugin plugin for WordPress is vulnerable to unauthorized access due to a missing capability check on several functions like export_forms(), import_forms(), update_fb_options(), and many more in all versions up to, and including, 3.1.7. This makes it possible for authenticated attackers, with subscriber-level access and above, to modify forms and various other settings.
The Classima WordPress theme before 2.1.11 and some of its required plugins (Classified Listing before 2.2.14, Classified Listing Pro before 2.0.20, Classified Listing Store & Membership before 1.4.20 and Classima Core before 1.10) do not escape a parameter before outputting it back in attributes, leading to Reflected Cross-Site Scripting
