CVE-2021-24292

The Happy Addons for Elementor WordPress plugin before 2.24.0, Happy Addons Pro for Elementor WordPress plugin before 1.17.0 have a number of widgets that are vulnerable to stored Cross-Site Scripting(XSS) by lower-privileged users such as contributors, all via a similar method: The Card widget accepts a title_tag parameter. Although the element control lists a fixed set of possible html tags, it is possible to send a save_builder request with the heading_tag set to script, and the actual title parameter set to JavaScript to be executed within the script tags added by the heading_tag parameter.
