When an application parses user-supplied URLs to store cookies, authentication credentials, or other kind of information, it is possible for an attacker to provide specially crafted URLs to make the application locate host-related information (e.g. cookies, authentication data) and send them to a different host than where it should, unlike if the URLs had been correctly parsed. The result of an attack may vary based on the application.","state":0,"publishedAt":"2019-06-07T17:50:33+00:00","modifiedAt":"2026-10-14T06:49:52.193+00:00","affected":[{"ecosystem":"Vendor product","name":"python","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"product\": \"python\",\n                    \"vendor\": \"Python\",\n                    \"versions\": [\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"affects 2.7, 3.5, 3.6, 3.7, >= v3.8.0a4 and < v3.8.0b1\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.0","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":9.8,"severity":"CRITICAL"}],"references":["https://python-security.readthedocs.io/vuln/urlsplit-nfkc-normalization2.html","https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2019-10160","https://github.com/python/cpython/commit/8d0ef0b5edeae52960c7ed05ae8a12388324f87e","https://github.com/python/cpython/commit/f61599b050c621386a3fc6bc480359e2d3bb93de","https://github.com/python/cpython/commit/250b62acc59921d399f0db47db3b462cd6037e09","https://github.com/python/cpython/commit/fd1771dbdd28709716bd531580c40ae5ed814468","https://security.netapp.com/advisory/ntap-20190617-0003/","https://access.redhat.com/errata/RHSA-2019:1587","https://lists.debian.org/debian-lts-announce/2019/06/msg00022.html","https://access.redhat.com/errata/RHSA-2019:1700","https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/44TS66GJMO5H3RLMVZEBGEFTB6O2LJJU/","https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/2ORNTF62QPLMJXIQ7KTZQ2776LMIXEKL/","https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/KRYFIMISZ47NTAU3XWZUOFB7CYL62KES/","https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/HQEQLXLOCR3SNM3AA5RRYJFQ5AZBYJ4L/","https://access.redhat.com/errata/RHSA-2019:2437","http://lists.opensuse.org/opensuse-security-announce/2019-08/msg00042.html","https://usn.ubuntu.com/4127-2/","https://usn.ubuntu.com/4127-1/","https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/NF3DRDGMVIRYNZMSLJIHNW47HOUQYXVG/","https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/ER6LONC2B2WYIO56GBQUDU6QTWZDPUNQ/","https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/E2HP37NUVLQSBW3J735A2DQDOZ4ZGBLY/","https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/M34WOYCDKTDE5KLUACE2YIEH7D37KHRX/","https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/JCPGLTTOBB3QEARDX4JOYURP6ELNNA2V/","https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/4X3HW5JRZ7GCPSR7UHJOLD7AWLTQCDVR/","http://lists.opensuse.org/opensuse-security-announce/2020-01/msg00040.html","https://lists.debian.org/debian-lts-announce/2020/07/msg00011.html","https://lists.apache.org/thread.html/r1b103833cb5bc8466e24ff0ecc5e75b45a705334ab6a444e64e840a0%40%3Cissues.bookkeeper.apache.org%3E","https://lists.debian.org/debian-lts-announce/2020/08/msg00034.html"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2019-10160","license":"CVE Program Terms of Use","key":"cve-program:CVE-2019-10160","identifiers":["CVE-2019-10160"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
