This CVE was published May 14, 2026 and is one of 40 known issues for this plugin.
Update, patch or deactivate.
No fixed release is identified. Update Bold Page Builder when a release after 5.6.8 becomes available; until then, disable and remove it when the site's risk warrants. The official upstream changelog lists version 5.9.6, which is newer than the published affected range. Its changelog does not clearly confirm this specific fix, so it is not counted as a known-safe release.
No confirmed safe version is listed. Consider a vendor-supported patch or temporarily restricting the affected functionality while you assess the risk.
Deactivate only when warranted by your risk profile, or when advised by your hosting provider in the limited circumstances where the vulnerability cannot otherwise be mitigated. If you’re unsure which action is appropriate, contact Fused or your hosting provider for guidance.
Technical description
The Bold Page Builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'text' attribute of the bt_bb_button shortcode in all versions up to, and including, 5.6.8. 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.
