Using its HSTS support, curl can be instructed to use HTTPS directly (instead of using an insecure cleartext HTTP step) even when HTTP is provided in the URL. This mechanism could be bypassed if the host name in the given URL uses IDN characters that get replaced with ASCII counterparts as part of the IDN conversion, e.g., using the character UTF-8 U+3002 (IDEOGRAPHIC FULL STOP) instead of the common ASCII full stop of U+002E (.). The earliest affected version is 7.77.0 2021-05-26.","state":0,"publishedAt":"2022-10-29T00:00:00+00:00","modifiedAt":"2026-10-14T18:26:44.484+00:00","affected":[{"ecosystem":"Vendor product","name":"n/a","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"n/a\",\n                    \"product\": \"n/a\",\n                    \"versions\": [\n                        {\n                            \"version\": \"n/a\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[],"references":["https://curl.se/docs/CVE-2022-42916.html","https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/HVU3IMZCKR4VE6KJ4GCWRL2ILLC6OV76/","https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/Q27V5YYMXUVI6PRZQVECON32XPVWTKDK/","https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/37YEVVC6NAF6H7UHH6YAUY5QEVY6LIH2/","https://security.netapp.com/advisory/ntap-20221209-0010/","https://security.gentoo.org/glsa/202212-01","http://www.openwall.com/lists/oss-security/2022/12/21/1","https://support.apple.com/kb/HT213604","https://support.apple.com/kb/HT213605","http://seclists.org/fulldisclosure/2023/Jan/20","http://seclists.org/fulldisclosure/2023/Jan/19"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2022-42916","license":"CVE Program Terms of Use","key":"cve-program:CVE-2022-42916","identifiers":["CVE-2022-42916"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
