Understanding the Beaver Builder Authorization Bypass Vulnerability
A notable security flaw has been discovered in the Beaver Builder – WordPress Page Builder plugin, specifically affecting all versions up to and including 2.9.4. This vulnerability, identified as an authorization bypass, could allow individuals with lower-level access on your WordPress site to significantly disrupt your website’s design and content integrity.
In simple terms, the issue stems from an oversight in the plugin’s code, where a function designed to disable the Beaver Builder layout on posts and pages doesn’t properly check if the user requesting this action has the necessary permissions. This means an authenticated attacker, even someone with just “contributor” privileges or higher, could disable the Beaver Builder layout on various posts and pages. Such an action could lead to immediate and visible changes on your website, potentially breaking layouts and causing content to display incorrectly.
