 "confidence": "high",
 "notes": "Found by Omer Mayraz (Legit Security), reported June 2025. The injection was hidden in invisible HTML comments in a pull-request description; data was encoded one ASCII character at a time as pre-signed Camo image URLs, defeating CSP with GitHub's own infrastructure. Several outlets misattribute the CVE as CVE-2025-53773 - that is the separate Copilot YOLO-mode RCE recorded elsewhere in this corpus.",
