What is CVE-2026-84744?

The WPForms Lite plugin for WordPress, versions 1.5.0.1 to 2.0.2, contains a flaw that fails to properly strip shortcode delimiters from user-submitted field values. This oversight enables unauthenticated individuals to execute arbitrary shortcodes registered on the website, potentially revealing sensitive details from non-public posts, including the information about attachments. Website administrators should be aware of this vulnerability and implement necessary security measures to prevent unauthorized access.
