Solace Extra AJAX action lets Subscribers alter post metadata and deactivate templates
Solace Extra before 1.6.1 exposes an AJAX action without capability or nonce checks. Any authenticated user, including a Subscriber, can update post metadata on arbitrary posts and deactivate the site's active templates. Because the action lacks a nonce, an attacker can also induce any logged-in user to submit the request through cross-site request forgery.

- Aug 09, 2026
This CVE was published Aug 09, 2026 and is one of 9 known issues for this plugin.
Update, patch or deactivate.
Update to 1.6.1 or later. Review arbitrary-post metadata and active template settings for unauthorized changes, restore deactivated templates from known-good configuration, and investigate low-privilege account activity and CSRF exposure.
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.
