Campaign configuration disclosure via unchecked AJAX action
Published Aug 27, 2026 · Updated Aug 27, 2026
Information disclosure in XLPlugins Finale Lite before 2.21.0 allows remote authenticated users to read sales-campaign configuration data. The wcct_quick_view_html AJAX action accepts an arbitrary campaign post ID and returns its configuration without checking the caller's capability. Subscriber-level access is sufficient to expose campaign rules and scheduling details, with no reported ability to alter them.
