Authorization bypass in Idvlabs Ontime through 04052026 allows remote attackers to read protected data via user-controlled identifiers. The public CNA record and government advisory do not identify the affected endpoint, parameter, or omitted authorization check. No authentication or user interaction is required, and the published impact is limited to disclosure rather than modification or service interruption.
