This module helps break Uniform Resource Locator (URL) strings into components. The issue involves how the urlparse method does not sanitize input and allows characters like '\\r' and '\\n' in the URL path. This flaw allows an attacker to input a crafted URL, leading to injection attacks. This flaw affects Python versions prior to 3.10.0b1, 3.9.5, 3.8.11, 3.7.11 and 3.6.14.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N","score":7.5},"cwes":["CWE-74"],"references":["https://bugs.python.org/issue43882","https://lists.debian.org/debian-lts-announce/2023/09/msg00022.html","https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/CSD2YBXP3ZF44E44QMIIAR5VTO35KTRB/","https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/UDBDBAU6HUPZHISBOARTXZ5GKHF2VH5U/","https://security.gentoo.org/glsa/202305-02"],"products":["fedoraproject:fedora","netapp:active_iq_unified_manager","netapp:hci","netapp:hci_compute_node","netapp:management_services_for_element_software","netapp:ontap_select_deploy_administration_utility","netapp:solidfire\\,_enterprise_sds_\\&_hci_storage_node","oracle:http_server","oracle:zfs_storage_appliance_kit","python:python"],"source":"nvd","synced_at":"2026-10-19T21:28:04.509275555+00:00"},"epss":{"cve":"CVE-2022-0391","score":0.08543,"percentile":0.9502,"date":"2026-10-25"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
