CVE-2026-78278Network attack vector

Protected-data disclosure via unchecked object key

Published Aug 24, 2026 · Updated Aug 24, 2026

Authorization bypass in WPManageNinja FluentBoards Pro 2.0.11 and earlier allows remote authenticated users to read protected objects. The plugin accepts a user-controlled object key without validating that the requesting Subscriber is authorized for the referenced object. Subscriber-level access is required; public advisories do not identify the affected endpoint or object type, and reported impact is limited to disclosure.
