## Technical details

The Bold Page Builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting (XSS) due to insufficient input sanitization and output escaping on the 'text' attribute of the 'bt_bb_button' shortcode. This vulnerability affects all versions up to and including 5.6.8. An authenticated attacker with contributor-level permissions or higher can exploit this by injecting malicious JavaScript into the shortcode attribute. Because the script is stored on the server, it will execute in the context of any user's browser who views the compromised page. A patch has been identified in recent changesets (3479329) to address the improper neutralization of input.
