Prior to 2.1.2, the Lokka-Microsoft tool in src/mcp/src/main.ts uses direct URL string concatenation to append the user-controlled path value to the management.azure.com base URL. A specially crafted path can alter URL authority parsing and cause an Azure Resource Manager bearer token to be sent to an unintended host. This issue is fixed in version 2.1.2.","state":0,"publishedAt":"2026-09-15T16:48:58.802+00:00","modifiedAt":"2026-09-15T19:01:50.538+00:00","affected":[{"ecosystem":"Vendor product","name":"lokka","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"merill\",\n                    \"product\": \"lokka\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 2.1.2\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N","score":8.7,"severity":"HIGH"}],"references":["https://github.com/merill/lokka/security/advisories/GHSA-g2gw-q38m-vjfc","https://github.com/merill/lokka/pull/47","https://github.com/merill/lokka/commit/babead878f44cc2face2f8ee55d8b706e420947e"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-58201","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-58201","identifiers":["CVE-2026-58201"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
