CVE-2026-8871

Beschreibung

The Formidable Kinetic plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the -kinetic_link- shortcode in versions up to, and including, 1.1.01. This is due to insufficient input sanitization and output escaping on user-supplied shortcode attributes (notably -window-, -class-, and -label-) in the FrmKinetic::link() function, which are concatenated directly into HTML attributes of an anchor tag. 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.
