Information disclosure via insecure resource initialization
Published Jun 19, 2026 · Updated Jun 19, 2026
Information disclosure in Microsoft GitHub Copilot Chat before 1.123.2 allows remote attackers to read data over a network. Microsoft identifies insecure default resource initialization but has not published the affected resource, default value, or disclosure path. Exploitation requires user interaction and no prior privileges; the published impact is limited to confidentiality, with no integrity or availability effect.
