CVE-2021-4334: fancy product designer vulnerability

What is known

The Fancy Product Designer plugin for WordPress is vulnerable to unauthorized modification of site options due to a missing capability check on the fpd_update_options function in versions up to, and including, 4.6.9. This makes it possible for authenticated attackers with subscriber-level permissions to modify site options, including setting the default role to administrator which can allow privilege escalation.

Business impact

Successful exploitation of CVE-2021-4334, a high vulnerability (CVSS 8.8) affecting fancy product designer, 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 fancy product designer 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.
