# CVE-2026-102435: Ultra Addons for Contact Form 7 <= 3.5.54 - Unauthenticated PHP Object Injection to Arbitrary File Deletion via CF7 Form Field

- Exploited (CISA KEV): no
- Published: 2026-11-02
- CVSS: 9.8 CRITICAL (v3.1)
- EPSS: no score
- CWE: CWE-502

The Ultra Addons for Contact Form 7 plugin for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation in the _getObjAttr function in all versions up to, and including, 3.5.54. This makes it possible for unauthenticated attackers to delete arbitrary files on the server, which can easily lead to remote code execution when the right file is deleted (such as wp-config.php). This requires the PDF Generator add-on to be active and a Contact Form 7 form to be configured for PDF generation, as the WPCF7_Submission POP gadget chain relies on CF7 being present to complete the file deletion via __destruct(). Note: This vulnerability can only be exploited when the PDF generator feature is enabled.

"No public claim" means no vendor statement names this CVE; "Before feed history" means the CVE is older than the vendor feed. In both cases generic rules may still block it.
