The Vulnerability Explained

In any Ocean Extra version up to and including 2.2.2, there is a cross-site request forgery (CSRF) vulnerability. In non-technical terms, this means an attacker could potentially activate unwanted plugins without permission.

This is extremely troubling. If malicious plugins were activated, they could steal data, modify content or cause other types of harm. Even if you have no enemies, attacks happen automatically so sites can be unwittingly weaponized.

Risks and Potential Impacts

A successful CSRF attack leading to unauthorized plugin activation opens the door for all kinds of exploitation. Sensitive data could be stolen, content altered or deleted, spam injected, and more.

Even if no visible changes occur right away, your site could be used as an attack platform against others. Cleaning up these vulnerabilities requires IT expertise many small business owners lack.

How to Remediate

Updating Ocean Extra by installing version 2.2.3 prevents this attack vector. But more broadly, staying on top of all plugin and WordPress core updates improves security and prevents vulnerabilities from being exploited before patches are available.

Past Vulnerabilities

This is far from the first vulnerability found in Ocean Extra. There have been 9 previous publicly disclosed vulnerabilities since July 2019. This reinforces the need to stay updated or consider alternate plugins.
