Jetformbuilder - Security Vulnerability (CVE-2026-121977)

The JetFormBuilder — Dynamic Blocks Form Builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'note (form field whose value is written to post meta `note`)' parameter in all versions up to, and including, 3.6.8 due to insufficient input sanitization and output escaping.

Successful exploitation requires a privileged user with the edit_others_posts capability to visit a form URL containing the attacker-created post ID,…

JetFormBuilder - Security Vulnerability (CVE-2026-19860)

The JetFormBuilder — Dynamic Blocks Form Builder WordPress plugin before 3.6.5.3 does not sufficiently restrict which PHP functions can be used as a custom field-validation callback, relying on a blocklist that omits a file-deletion function, allowing users able to manage forms to cause arbitrary files on the server to be deleted. The deletion itself is carried out when the form is submitted, which requires no authentication.

Jetformbuilder - Security Vulnerability (CVE-2026-12793)

The JetFormBuilder — Dynamic Blocks Form Builder plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 3.6.2. This is due to the plugin not validating that a submitted form ID belongs to a JetFormBuilder form before parsing the referenced post's content as form schema and executing an Advanced Validation server-side callback. This makes it possible for unauthenticated attackers to create a new administrator-level user account.

JetFormBuilder - Improper Input Validation (CVE-2026-19862)

The JetFormBuilder WordPress plugin before 3.6.5.2 does not validate or strip line breaks from address values it sources from submitted form fields before adding them to the headers of the e-mails it sends, allowing unauthenticated users to inject arbitrary e-mail headers, add hidden recipients and spoof the sender. Exploitation requires the site to be configured to take one of the message's addresses from a form field.
