Description
The UiCore Elements plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the Contact Form widget in all versions up to, and including, 1.3.17 due to insufficient input sanitization and output escaping on widget settings such as field labels, field values, option labels, acceptance text, the inline list setting and HTML field content. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This is the fix CVE-2026-39708 now describes (revised by its CNA, Patchstack, to versions up to and including 1.3.17, fixed in 1.3.18); the feed copy in our data still says fixed in 1.3.14.
