8.1High

CVE-2026-16948

The Solace Extra WordPress plugin before 1.6.1 does not perform capability checks in several of its AJAX actions and exposes the nonce that protects them on admin pages reachable by low-privileged users, allowing users with a role as low as Subscriber to modify site-wide presentation settings and delete imported site-builder content.

What this means for your business

  • An attacker can use it remotely, over a network, with an ordinary user login, and without anyone at your company clicking anything.
  • FIRST's prediction model gives it a 0.2% chance of attack attempts being seen in the next 30 days, ranking above 11% of all known flaws.

What to do

  1. 1Ask your IT team or provider whether any of your systems use the affected product.
  2. 2If you do, follow the vendor's guidance. No patch reference has been published yet.
