PHP_SELFish Part 2 – Reflected XSS in Easy Social Icons

WordFence - 

Today’s post is part two of a two part blog post. It describes a cross site scripting in the Easy Social Icons plugin that the PHP_SELF variable. In yesterday’s post, we described another plugin, underConstruction, suffering from a similar vulnerability related to the use of PHP_SELF.

On August 16, , the Threat Intelligence team attempted to initiate disclosure for a reflected vulnerability in Easy Social Icons, a WordPress plugin with over 40,000 installations.

After 2 weeks without a response, we forwarded the issue to the WordPress plugins team on August 30, 2021. An initial , version 3.0.9, was released the next day, on August 31, 2021.

A firewall rule protecting against this vulnerability was released to Wordfence Premium users on August 16, 2021, and became available to sites using the free version of Wordfence on September 15, 2021.

Newer versions of the plugin also contain patches for additional XSS vulnerabilities, and all Wordfence users are protected against these vulnerabilities by our firewall’s built-in XSS protection. If you’re not using Wordfence, we recommend that you immediately upgrade to version 3.1.3 of the Easy Social Icons plugin.
