Authenticated Option Deletion Vulnerability in My WP Translate

Recently we went to check on a report of a cross-site scripting (XSS) vulnerability in the plugin My WP Translate and while looking into that we noticed that there were a number AJAX accessible functions that didn’t have the proper protection so that anyone logged in could access them. That is an all too common situation. On a lot of websites that wouldn’t matter much since the only user account is an Administrator, so that if someone gains access to the account they can do whatever they want already, or only trusted individuals have accounts. For websites that do allow untrusted users to have accounts taking extra precautions when it comes to plugins is a good idea.

That has lead to us finding quite a few vulnerabilities in the current versions of plugins. In attempt to catch more of this type of issue we have been looking around for more data so that we can catch more of these vulnerabilities. That lead us to look at the Social Media and Share Icons (Ultimate Social Media) plugin, despite it looking like it might not have been the target of a hacker. While reviewing that we found a fairly serious vulnerability, though not one that hackers would likely be interested in exploiting.
