The Video Conferencing with Zoom plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'zoomrecordingsbymeeting' shortcode in all versions up to, and including, 4.4.4 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers with contributor-level and above permissions to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

The Video Conferencing with Zoom plugin for WordPress is vulnerable to Sensitive Information Exposure due to hardcoded encryption key on the 'vczapiencryptdecrypt' function in versions up to, and including, 4.2.1.

The Video Conferencing with Zoom WordPress plugin before 3.8.17 does not have authorisation in its vczapigetwpusers AJAX action, allowing any authenticated users, such as subscriber to download the list of email addresses registered on the blog
