The OceanWP theme for WordPress is vulnerable to Cross-Site Request Forgery in versions 4.0.9 to 4.1.1. This is due to missing or incorrect nonce validation on the oceanwp_notice_button_click() function. This makes it possible for unauthenticated attackers to install the Ocean Extra plugin via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.

Multiple plugins for WordPress are vulnerable to Stored Cross-Site Scripting via the plugin's bundled Magnific Popups library (version 1.1.0) in various versions due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. NOTE: This vulnerability was fixed in the upstream library (Magnific Popups version 1.2.0) by disabling the loading of HTML within certain fields by default.
