CVE-2026-58201Network attack vectorHinoki check available

Azure token disclosure via authority-changing path

Published Sep 15, 2026 · Updated Sep 15, 2026

SSRF in Merill Fernando Lokka before 2.1.2 allows remote attackers to disclose Azure Resource Manager bearer tokens via crafted paths. The Lokka-Microsoft tool concatenates its user-controlled path onto the management.azure.com base URL, allowing the path to change the parsed authority. An attacker must be able to supply an Azure API path to the MCP tool; exploitation sends its Azure bearer token to an attacker-controlled host.
