CVE-2026-6171: 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 'target' parameter of the plugin's bt_bb_icon shortcode in all versions up to, and including, 5.7.2 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-2026-6171 is a stored cross-site scripting vulnerability in the Bold Page Builder WordPress plugin. The flaw exists due to insufficient input sanitization and output escaping on the 'target' parameter of the bt_bb_icon shortcode. Authenticated attackers with Contributor-level privileges or above can exploit this to inject arbitrary web scripts into pages, which execute in the context of users who access those pages. This vulnerability affects all versions up to and including 5.7.2.
Potential Impact
An attacker with Contributor-level access or higher can inject malicious scripts that execute in the browsers of users viewing the compromised pages. This can lead to information disclosure or session hijacking. The CVSS score of 6.4 (medium severity) reflects the network attack vector, low attack complexity, and the requirement for privileges but no user interaction.
Mitigation Recommendations
No official patch or fix is currently documented. Users should check the vendor's advisory for updates. Until a fix is available, restrict Contributor-level access to trusted users and consider removing or disabling the vulnerable shortcode if possible.
