FKIE_CVE-2026-8938

Vulnerability from fkie_nvd - Published: 2026-05-27 07:16 - Updated: 2026-06-17 11:04
Severity
4.3 (Medium) - CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:N
Summary
The auto making JSON-LD plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 4.5.3. This is due to missing or incorrect nonce validation on the amJL_certification function. This makes it possible for unauthenticated attackers to update the plugin's license key option, and subsequently trigger license validation and pro feature installation on the victim site without the administrator's consent via a forged request granted they can trick a site administrator into performing an action such as clicking on a link. Successful exploitation can trigger downstream calls to amJL_is_license_valid() and amJL_download_and_install_pro_features(), meaning the impact extends beyond a simple settings change to unauthorized installation of plugin components.
