CVE-2024-38183Network attack vector

Unauthenticated privilege escalation via undisclosed SSRF

Published Sep 17, 2024 · Updated Aug 10, 2026

Improper access control in Microsoft GroupMe allows remote attackers to elevate privileges through an unauthenticated network request. Microsoft classifies the flaw as server-side request forgery but has not published the affected endpoint or the access-control operation performed on attacker-controlled input. No authentication or user interaction is required, and successful exploitation grants elevated privileges in the hosted GroupMe service.
