Keeping your WordPress website secure is a constant effort, and understanding potential weaknesses in your plugins is a big part of that. Today, we’re discussing a significant security flaw found in the Elegant Themes Bloom plugin, identified as CVE-2016-11003. This issue, classified as a privilege escalation vulnerability, means that if exploited, a logged-in user with lower permissions could gain unauthorized access to higher-level functions on your website.
In simple terms, privilege escalation is like someone with a guest pass suddenly being able to access the manager’s office. For a WordPress site, this could mean an attacker, even with limited access, might be able to take control of your site, modify content, or worse. This vulnerability was first discovered in February 2016, with a fix released shortly after, but it’s crucial to ensure your site is protected.

Affected Products
This vulnerability impacts specific versions of the Elegant Themes Bloom plugin for WordPress. Any installations running Bloom plugin versions earlier than 1.1.1 are at risk. Other Elegant Themes products like Divi, Divi Builder, Extra, and Monarch were also affected by related vulnerabilities around the same time, highlighting the importance of keeping all themes and plugins updated.
Current Status

This is particularly dangerous for sites that allow user registrations, even if those users are typically considered “untrusted.”
Possible Solutions
The most effective and straightforward solution to protect your WordPress site from CVE-2016-11003 is to update your Elegant Themes Bloom plugin to version 1.1.1 or later immediately. If you are using an outdated version, upgrading will apply the necessary security patches and close the door to potential attackers.
