Description
Ultra Addons for Contact Form 7 <= 3.5.54 - Unauthenticated Arbitrary File Read via CF7 Field Value in mPDF WriteHTML SVG Parser
The Ultra Addons for Contact Form 7 plugin for WordPress is vulnerable to Directory Traversal in all versions up to, and including, 3.5.54 via the uacf7_wpcf7_mail_components function. This makes it possible for unauthenticated attackers to read the contents of arbitrary files on the server, which can contain sensitive information. Exploitation requires the PDF Generator addon to be active and an administrator-configured PDF body template to be enabled for the targeted contact form.
