Descriptions

Insecure Deserialization in the Newsletter plugin before 6.8.2 for WordPress allows authenticated remote attackers with minimal privileges (such as subscribers) to use the tpnc_render AJAX action to inject arbitrary PHP objects via the options[inline_edits] parameter. NOTE: exploitability depends on PHP objects that might be present with certain other plugins or themes.
