What the vulnerability does
The Bold Page Builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin 'bt_bb_tabs' shortcode in all versions up to, and including, 5.5.1 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.
Explanation of Vulnerability in Simple Terms
Bold Page Builder versions up to 5.5.1 contain a cross-site scripting vulnerability that allows authenticated users to inject malicious scripts affecting other users and site functionality. An attacker with low-level access can craft malicious input that executes in other users' browsers or impacts site behavior. The vulnerability has network-wide scope, meaning injected content can affect multiple parts of the site beyond the vulnerable component.
What an attacker can do
Inject malicious scripts that execute in other users' browsers or alter site functionality.
Potential impact on your site
Authenticated users can inject scripts affecting other users' sessions and site behavior; requires immediate patching.
Conditions required to exploit
Attacker must have a low-privilege account on the site; no user interaction required.
