Description

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.

Security Summary

CVE-2024-8420 is a privilege escalation vulnerability in the DHVC Form plugin for WordPress, affecting all versions up to and including 2.4.7. The flaw stems from the plugin permitting users to supply the 'role' field during registration, which allows attackers to self-assign elevated privileges.

Unauthenticated attackers can exploit this vulnerability over the network with low attack complexity and no user interaction, as reflected in its CVSS v3.1 base score of 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H). Exploitation enables remote registration as a site administrator, granting full control over the WordPress installation and potentially leading to unauthorized access, data exfiltration, modification, or deletion (related to CWE-266 and CWE-269).
