The Bricks theme for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 1.9.6.1. This is due to insufficient validation checks placed on the createautosave AJAX function. This makes it possible for authenticated attackers, with contributor-level access and above, to execute arbitrary PHP code with elevated (administrator-level) privileges. NOTE: Successful exploitation requires (1) the Bricks Builder to be enabled for posts (2) Builder access to be enabled for contributor-level users, and (3) "Code Execution" to be enabled for administrator-level users within the theme's settings.

The Bricks theme for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘customTag' attribute in versions up to, and including, 1.10.1 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with access to the Bricks Builder (admin-only by default), to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This becomes more of an issue when Bricks Builder access is granted to lower-privileged users.

The Bricks theme for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 1.8.1. This is due to missing or incorrect nonce validation on the 'savesettings' function. This makes it possible for unauthenticated attackers to modify the theme's settings, including enabling a setting which allows lower-privileged users such as contributors to perform code execution, via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.

The Bricks theme for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 1.8.1. This is due to missing or incorrect nonce validation on the 'resetsettings' function. This makes it possible for unauthenticated attackers to reset the theme's settings via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.

The Bricks Builder plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 1.9.8 via the postId parameter due to missing validation on a user controlled key. This makes it possible for authenticated attackers, with Contributor-level access and above, to modify posts and pages created by other users including admins. As a requirement for this, an admin would have to enable access to the editor specifically for such a user or enable it for all users with a certain user account type.

The Bricks theme for WordPress is vulnerable to remote code execution due to the theme allowing site editors to include executable code blocks in website content in versions 1.2 to 1.5.3. This, combined with the missing authorization vulnerability (CVE-2022-3400), makes it possible for authenticated attackers with minimal permissions, such as a subscriber, can edit any page, post, or template on the vulnerable WordPress website and inject a code execution block that can be used to achieve remote code execution.

The Bricks theme for WordPress is vulnerable to authorization bypass due to a missing capability check on the brickssavepost AJAX action in versions 1.0 to 1.5.3. This makes it possible for authenticated attackers with minimal permissions, such as a subscriber, to edit any page, post, or template on the vulnerable WordPress website.
