Prior to version 1.4.3, the `HTTPUEContextTransfer` handler in `internal/sbi/api_communication.go` does not include a `default` case in the `Content-Type` switch statement. When a request arrives with an unsupported `Content-Type`, the deserialization step is silently skipped, `err` remains `nil`, and the processor is invoked with a completely uninitialized `UeContextTransferRequest` object. Version 1.4.3 contains a fix.","state":0,"publishedAt":"2026-04-21T23:54:36.727+00:00","modifiedAt":"2026-04-22T13:11:10.206+00:00","affected":[{"ecosystem":"Vendor product","name":"amf","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"free5gc\",\n                    \"product\": \"amf\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 1.4.3\",\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:N/VI:L/VA:N/SC:N/SI:N/SA:N/E:P","score":5.5,"severity":"MEDIUM"}],"references":["https://github.com/free5gc/free5gc/security/advisories/GHSA-r99v-75p9-xqm5","https://github.com/free5gc/amf/releases/tag/v1.4.3"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-41136","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-41136","identifiers":["CVE-2026-41136"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
