Authenticated privilege escalation via undisclosed authentication flaw
Published Jun 18, 2026 · Updated Jun 18, 2026
Improper authentication in Microsoft Azure AI Bot Service allows remote authenticated users to elevate privileges over a network. Microsoft has not published the affected authentication locus or the incorrect operation responsible for the authorization failure. Existing low-privilege access is required, and exploitation changes authorization across a security boundary without disclosed confidentiality or availability impact.
