Technical Summary
CVE-2026-18594 is an authorization bypass vulnerability (CWE-862) in the Advanced Contact form 7 DB WordPress plugin by vsourz1td. The plugin fails to properly verify that a user is authorized to perform CSV import actions, enabling authenticated users with custom-level access or above to import forged submission records into any Contact Form 7 form. This affects all versions up to and including 2.1.3. The CVSS 3.1 base score is 4.3 (medium severity), reflecting low complexity and low privileges required, with impact limited to integrity (no confidentiality or availability impact).
