This CVE was published Aug 03, 2026 and is one of 1 known issue for this plugin.

Update, patch or deactivate.

Update to a corrected sm page duplicator release after 1.0.0 when available. Until then, restrict page duplication to trusted administrators or replace the plugin, and investigate unexpected duplication activity by Editor accounts.

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.
