CVE-2025-15267 boldthemes CVE debrief

Who should care

Defenders responsible for WordPress sites using the Bold Page Builder plugin should assess exposure and prioritize verification and remediation. This includes reviewing compensating controls for exposed systems while remediation is scheduled and verified, and tracking exceptions, retesting remediated assets, and closing the item only after evidence is documented.

Why it matters

The Bold Page Builder plugin for WordPress has a Stored Cross-Site Scripting vulnerability, allowing authenticated attackers to inject arbitrary web scripts. Defenders should prioritize verification and remediation to prevent exploitation.

• Authenticated attackers with contributor-level access and above can inject arbitrary web scripts in pages.
• Injected scripts will execute when a user accesses an injected page.
• Defenders must verify and update the Bold Page Builder plugin to prevent exploitation.
• Remediation priority is high for WordPress sites using the affected plugin versions.

Technical summary

The Bold Page Builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's bt_bb_accordion_item shortcode in all versions up to, and including, 5.6.1 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.
