What is CVE-2026-92212?

The JetFormBuilder plugin for WordPress is susceptible to Reflected Cross-Site Scripting (XSS) via the 'jfb_xss' parameter in the Calculated Field. This vulnerability exists due to inadequate sanitization of user inputs, which allows attackers to inject arbitrary scripts into pages that may execute when a user interacts with a compromised link. For exploitation, a specific form setup is necessary, utilizing both a URL Query Variable preset field and a Calculated Field, features commonly available in JetFormBuilder. Users are advised to conduct updates and ensure proper input validation to mitigate potential security risks.

Affected Version(s)

JetFormBuilder — Dynamic Blocks Form Builder 0 <= 3.6.5.3
