What is known
The DHVC Form plugin for WordPress is vulnerable to privilege escalation in all versions up to, and including, 2.4.7. This is due to the plugin allowing a user to supply the 'role' field when registering. This makes it possible for unauthenticated attackers to register as an administrator on sites.
Business impact
Successful exploitation of CVE-2024-8420, a critical vulnerability (CVSS 9.8) affecting dhvc form, 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 dhvc form 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.
