Emerging Threat: (CVE-2026-69197) Umbraco CMS Protected Content Disclosure via Delivery API Expansion
CVE-2026-69197 is an authorization flaw in the Content Delivery API of Umbraco CMS, an open source ASP.NET content management system. The Delivery API enforces member and Public Access checks on the node a caller directly requests, but it does not apply those same checks to nodes referenced through Content Picker or Multi-Node Tree Picker properties. The gap extends to pickers nested inside Block List, Block Grid, and Rich Text Editor blocks.
