WordPress Plugin Vulnerabilities
WP VR < 8.3.15 - Unauthenticated Plugin Downgrade leading to XSS
Description
The plugin does not authorisation and CSRF in a function hooked to admin_init, allowing unauthenticated users to downgrade the plugin, thus leading to Reflected or Stored XSS, as previous versions have such vulnerabilities.
v3.8.15 partially fixed the issue as the wrong capability check was used
