What the vulnerability does
01Description
The Slider Revolution plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘htmltag’ parameter in all versions up to, and including, 6.7.7 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. By default, this can only be exploited by administrators, but the ability to use and configure Slider Revolution can be extended to authors.
Explanation of Vulnerability in Simple Terms
02Summary
Slider Revolution versions up to 6.7.7 contain a cross-site scripting vulnerability that allows authenticated users to inject malicious scripts. The vulnerability has a changed scope, meaning injected code can affect other users and site functionality beyond the plugin itself. Site administrators should update to a version newer than 6.7.7 to remediate this issue.
