In the high-stakes world of vulnerability management, nothing is quite as frustrating—or as philosophically intriguing—as the 'Rejected' CVE. CVE-2025-66649 represents a classic case of the 'Phantom Vulnerability': a security identifier that was reserved, briefly existed in the ether, and was subsequently executed by the CNA (GitHub) before it could cause real damage. This report analyzes the lifecycle of a rejected CVE, the psychology of false positives, and why this specific record is a digital ghost town.

CVE-2025-66649 has been officially REJECTED by its assigner (GitHub). It is not a security vulnerability. There is no patch, no exploit, and no impact—other than the wasted time of security analysts chasing ghosts. No action is required.
