CVE-2026-18594: VSOURZ1TD Advanced Contact Form 7 DB

Medium severity, CVSS 4.3. EPSS: 0.2% chance of exploitation in the next 30 days.

The Advanced Contact form 7 DB plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 2.1.3. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with custom-level access and above, to import forged CSV submission records into any Contact Form 7 form managed by the plugin.
