NextScripts: Social Networks Auto-Poster WordPress Privilege Escalation Bypass
Description

The NextScripts: Social Networks Auto-Poster plugin for WordPress is vulnerable to authorization bypass due to missing capability checks on multiple user privilege/security functions provided in versions up to, and including 4.3.17.
