CWE-352: Cross-Site Request Forgery (CSRF)
Reaching this weakness in Himer - Social Questions and Answers WordPress Theme <= 2.1.0 takes a caller who can reach the endpoint. Cross-site request forgery abuses the fact that browsers attach a victim's cookies to any request, so a state-changing action that only checks who you are, not whether you meant to act, can be triggered from another site.
An attacker who gets a logged-in user to load a crafted page can perform that action as them, with the impact scaling to whatever the victim's role is allowed to do. For Himer - Social Questions and Answers WordPress Theme the fix is 2.1.1: builds <= 2.1.0 are affected, anything from 2.1.1 onward is not.
Remediation
Update to version 2.1.1, or a newer patched version
