- Sep 11, 2026
This CVE was published Sep 11, 2026 and is one of 40 known issues for this plugin.
Update, patch or deactivate.
Update Bold Page Builder to 5.9.10 or later. The authoritative affected data explicitly marks 5.9.10 unaffected. The application-level fix must sanitize attacker-controlled content when saved and escape it for its exact output context when rendered.
A safe version is available, so updating to that version or later is the preferred remediation. If an immediate update is not practical, consider a targeted application patch or temporarily restricting the affected functionality.
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.
