CVE-2024-13420: april vulnerability

What is known

Multiple plugins and/or themes for WordPress are vulnerable to unauthorized access due to a missing capability check on several AJAX actions like 'gsf_reset_section_options', 'gsf_reset_section_options', 'gsf_create_preset_options' and more in various versions. This makes it possible for authenticated attackers, with Subscriber-level access and above, to reset and modify some of the plugin/theme settings. This issue was escalated to Envato over two months from the date of this disclosure and the issues, while partially patched, are still vulnerable.

Business impact

Successful exploitation of CVE-2024-13420, a medium vulnerability (CVSS 4.3) affecting april, may affect the confidentiality, integrity or availability of the vulnerable environment. The exact impact depends on the installed version, exposed interfaces and deployment configuration.

Recommended administrator action

Confirm whether april is present and compare installed versions with the vendor advisory and NVD record. Apply the vendor patch or documented mitigation; until remediation is complete, reduce exposure of affected interfaces, review relevant logs and monitor for indicators of exploitation. DataHouse can support version verification, managed patching, network exposure reduction, log review and backup validation for dedicated, cloud and colocated environments.
