Deeper analysis
The Thumbnail carousel slider plugin for WordPress, also known as wp-responsive-thumbnail-slider, is affected by a reflected cross-site scripting vulnerability in versions up to and including 1.1.9. The flaw, tracked as CWE-79, arises from insufficient input sanitization and output escaping on the search_term parameter and carries a CVSS 3.1 score of 6.1.
