This CVE was published Sep 23, 2026 and is one of 17 known issues for this plugin.
Update, patch or deactivate.
Update to 2.9.20 or later, preferably the current supported release. Require the appropriate capability and per-object ownership check inside the affected handler before reading or changing protected state. Restrict access to the affected functionality until the upstream update is applied.
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.
