What to do

Update, patch or deactivate.

No fixed release is confirmed in the authoritative export. Obtain an upstream remediation that enforces product-editing permissions and ownership, validates a nonce, sanitizes popup configuration on input, and escapes each value for its output context. Consider deactivating the plugin until a confirmed fix is available.

No confirmed safe version is listed. Consider a vendor-supported patch or temporarily restricting the affected functionality while you assess the risk.

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.
