WordPress < 4.4.1 class-wp-theme.php XSS

medium Nessus Plugin ID 87921

Synopsis

The PHP application running on the remote web server is affected by a cross-site scripting vulnerability.

Description

According to its self-reported version number, the WordPress application running on the remote web server is prior to 4.4.1.
It is, therefore, affected by a cross-site scripting (XSS) vulnerability due to improper validation of user-supplied input to the file wp-includes/class-wp-theme.php before returning it in error messages. A remote attacker can exploit this, via a crafted request, to execute arbitrary script code in the user's browser session.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade to WordPress version 4.4.1 or later.
