Description
The Ajax Search Lite plugin for WordPress is vulnerable to Stored Cross-Site Scripting in all versions up to, and including, 4.14.5, due to the front-end script reading search instance settings from every '.asl_init_data' element on the page, so a later element overrides the real one, and navigating to the configured home or redirect URL without checking its scheme. This makes it possible for authenticated attackers with contributor-level access and above to place an element with forged settings in a post, so that a javascript: URL executes arbitrary web scripts when a user searches with the site's search bar on that page. The search bar must precede the post content.
