CVE-2026-15630
A critical flaw allows a non‑global organization administrator in one tenant to bypass tenant boundaries and delete, create, or modify resources in any other tenant. The vulnerability arises from a mismatch between the authorization check and the action performed. It can be exploited without user interaction.
No official fix yet. If none appears within 45 days of first tracking, this entry is removed automatically.
Who is affected
Non‑global organization administrators who have access to one tenant but not to others. Any tenant that shares the same underlying platform is at risk.
Real-world impact
