CVE-2026-73061 is a critical improper access control vulnerability in Scriban affecting versions before 7.2.2. The flaw resides in TypedObjectAccessor, which fails to enforce CLR setter visibility when template code writes object properties. As a result, templates can modify properties that should not be writable through normal access controls, including properties with private, internal, or init-only setters. The issue also enables mass assignment against properties with public setters. Successful exploitation allows untrusted template code to alter live host application objects during rendering, and those changes can persist after template execution completes.
