The Ocean Extra plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the Flickr widget in all versions up to, and including, 2.2.8 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.

The Ocean Extra WordPress plugin before 2.0.5 unserialises the content of an imported file, which could lead to PHP object injections issues when a high privilege user import (intentionally or not) a malicious Customizer Styling file and a suitable gadget chain is present on the blog.

The Ocean Extra WordPress plugin before 2.1.3 does not ensure that the template to be loaded via a shortcode is actually a template, allowing any authenticated users such as subscriber to retrieve the content of arbitrary posts, such as draft, private or even password protected ones.

includes/wizard/wizard.php in the Ocean Extra plugin through 1.5.8 for WordPress allows unauthenticated options changes and injection of a Cascading Style Sheets (CSS) token sequence.

The Ocean Extra WordPress plugin before 1.9.5 does not escape generated links which are then used when the OceanWP is active, leading to a Reflected Cross-Site Scripting issue
