CVE-2026-16965Public exploitNetwork attack vector

Subscriber-level metadata manipulation via unchecked AJAX

Published Aug 9, 2026 · Updated Aug 9, 2026

Missing authorization in SolaceWP Solace Extra before 1.6.1 allows remote authenticated users to alter arbitrary post metadata. The solace_update_sitebuilder_status AJAX action accepts post_id, part, and status values without a capability check or nonce validation, then writes status metadata or clears active template state. Subscriber-level access is sufficient for direct requests, while a crafted cross-site request can act through any logged-in user's session; the bounded impact is unauthorized metadata changes and active-template deactivation.
