CVE-2026-45499 is a critical server-side request forgery (SSRF) vulnerability in Microsoft Azure OpenAI. According to the provided content, the flaw is caused by insufficient validation of outbound request targets, allowing an authorized low-privilege user to induce the service to make server-side requests to restricted internal or metadata endpoints. By abusing Azure OpenAI’s server-side network context as a proxy, an attacker could reach sensitive internal resources that should not be directly accessible and leverage that access to elevate privileges. The provided content associates the issue with CVSS v3.1 9.9 and the vector CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H.
