Security readout for executives and security teams
Plain-English summary
CVE-2026-25451 is a stored cross-site scripting issue in the WordPress Bold Page Builder plugin through version 5.6.9. An authenticated user could store malicious script content that later runs when another user views affected pages. This is a medium-severity website integrity and account-risk issue, especially for sites with multiple content contributors.
Executive priority
Prioritize remediation for public-facing WordPress sites, especially those with multiple content contributors. This is not currently evidenced as actively exploited in the provided sources, but stored XSS can affect customer trust, site integrity, and administrator accounts.
Technical view
The CVE describes CWE-79 improper input neutralization during page generation in boldthemes Bold Page Builder. CVSS 3.1 is 6.5 with network attack vector, low complexity, low privileges required, user interaction required, and scope changed. The vulnerable range is reported as Bold Page Builder through 5.6.9.
Likely exposure
Exposure is limited to WordPress sites using the Bold Page Builder plugin at version 5.6.9 or earlier. Risk is higher where contributor, author, editor, or other lower-privileged accounts can create or edit content processed by the plugin.
Exploitation context
The provided sources do not show active exploitation or CISA KEV listing. Exploitation requires a logged-in user and a victim viewing affected generated content. Stored XSS can support session theft, content tampering, redirects, or administrative action abuse depending on victim privileges and site controls.
Researcher notes
There is a minor source inconsistency: the CVE description says through 5.6.9, while the Patchstack reference URL title mentions 5.6.4. Treat 5.6.9 and earlier as in scope unless vendor guidance narrows the affected range.
Mitigation direction
- Inventory WordPress sites for Bold Page Builder installations and versions.
- Check vendor or Patchstack guidance for a fixed version or official workaround.
- Update the plugin if an official patched version is available.
- Disable or remove the plugin where it is not business-critical.
- Restrict content-editing privileges to trusted users until remediation is complete.
Validation and detection
- Confirm whether Bold Page Builder is installed on each WordPress site.
- Record plugin version and flag versions 5.6.9 or earlier.
- Review user roles that can create or edit plugin-managed content.
- Check web application logs for unusual authenticated content changes.
- Verify remediation by confirming the plugin is updated, disabled, or removed.
