What to do

Update, patch or deactivate.

Update to a corrected release after 3.1.0. Review Powerkit nav attributes, remove payloads, and invalidate privileged sessions where warranted.

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.
