FKIE_CVE-2026-18594

Vulnerability from fkie_nvd - Published: 2026-09-10 04:17 - Updated: 2026-09-10 14:39
Severity
4.3 (Medium) - CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N
Summary
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.
