1) Cross-site scripting


The vulnerability allows a remote attacker to perform cross-site scripting attacks.

The vulnerability exists due to usage of the eval() JavaScript call on data passed via the  "swp_url" HTTP GET parameter to "/wp-admin/admin-post.php" script, when "swp_debug" is set to "load_options", allowing to permanently inject and execute arbitrary JavaScript code on the website. A remote unauthenticated attacker can store a specially crafted JavaScript code into database and execute it in browser of every website visitor.

Note: this vulnerability is being actively exploited in the wild.

Exploitation example:



Update to version 3.5.3.
