Microsoft Fixes Critical Entra ID Flaw

The rarity here is the timing: a maximum-severity remote-code-execution flaw in a core identity service was fixed before public disclosure, and Microsoft found no evidence of exploitation. Entra ID underpins authentication for a vast number of enterprises, so a pre-disclosure patch removes what would otherwise be a race between defenders and attackers. The absence of observed exploitation is reassuring but not proof of absence, and the open question is whether proof-of-concept code or scanning activity emerges now that the patch is public.
