no vendor or government report was provided. No dates of occurrence or detection are stated, and the article date is not treated as a disclosure date. The developer of the Copilot agent, the responsible party and the deployment context are not stated, so those fields are omitted. No count of affected repositories, users or records is given. The file_read tool is named in the source but only run_in_terminal is listed in tools_granted because the quoted sentence names that tool. Judgements made: autonomy_level full-auto from the 'autonomous coding agent' wording and the absence of any approval step; detection_method public_researcher because Orca researchers uncovered the flaw; severity moderate because the source states a bounded scope of one repository with read and write access; the Microsoft patch is mapped to J1 as a judgement since the source does not name the control changed; the advice controls are mapped from Orca's recommendations. The source does not state whether the flaw was exploited outside research, so no harm is recorded as materialised. Control F4 is marked missing based on the statement that no visible alert was generated.
