CVE-2024-8420
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedThe 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.
