What is CVE-2025-12652?

The Ungapped Widgets plugin for WordPress is susceptible to a Stored Cross-Site Scripting (XSS) vulnerability via the 'prefillvalues' parameter in the ungapped-form shortcode. This issue arises from inadequate input sanitization and output escaping for user-supplied inputs. Authenticated attackers with contributor-level access or higher can inject arbitrary web scripts, which will execute when users visit affected pages. Ensuring proper input handling can mitigate this risk and protect users from potential exploitation.
