CVE-2026-88037: CWE-79 Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in boldthemes Bold Page Builder
The Bold Page Builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the `title` attribute of the `bt_bb_service` shortcode in all versions up to, and including, 5.7.2. This is 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.
AI Analysis
Technical Summary
CVE-2026-88037 is a stored XSS vulnerability in the Bold Page Builder WordPress plugin. It arises from insufficient sanitization and escaping of user-supplied input in the 'title' attribute of the 'bt_bb_service' shortcode. This allows authenticated users with Contributor or higher privileges to inject arbitrary JavaScript that executes in the context of users viewing the injected pages. The vulnerability affects all plugin versions up to 5.7.2 inclusive.
Potential Impact
An attacker with Contributor-level access or above can inject malicious scripts that execute in the browsers of users who visit the compromised pages. This can lead to theft of user credentials, session hijacking, or other actions performed with the privileges of the victim user. The vulnerability does not affect unauthenticated users directly and does not impact availability.
Mitigation Recommendations
No official patch or fix is currently documented. Users should upgrade beyond version 5.7.2 if a fixed version becomes available. Until then, restrict Contributor-level access to trusted users only and monitor for suspicious activity. Check the vendor's advisory for updates on remediation.
