These module imports were intentionally deferred to increase startup time of the pip CLI. The patch changes self-update functionality to run before wheels are installed to prevent newly-installed modules from being imported shortly after the installation of a wheel package. Users should still review package contents prior to installation.","affected":[{"package":{"name":"pip","ecosystem":"PyPI","purl":"pkg:pypi/pip"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"26.1"}]}],"versions":["0.2","0.2.1","0.3","0.3.1","0.4","0.5","0.5.1","0.6","0.6.1","0.6.2","0.6.3","0.7","0.7.1","0.7.2","0.8","0.8.1","0.8.2","0.8.3","1.0","1.0.1","1.0.2","1.1","1.2","1.2.1","1.3","1.3.1","1.4","1.4.1","1.5","1.5.1","1.5.2","1.5.3","1.5.4","1.5.5","1.5.6","10.0.0","10.0.0b1","10.0.0b2","10.0.1","18.0","18.1","19.0","19.0.1","19.0.2","19.0.3","19.1","19.1.1","19.2","19.2.1","19.2.2","19.2.3","19.3","19.3.1","20.0","20.0.1","20.0.2","20.1","20.1.1","20.1b1","20.2","20.2.1","20.2.2","20.2.3","20.2.4","20.2b1","20.3","20.3.1","20.3.2","20.3.3","20.3.4","20.3b1","21.0","21.0.1","21.1","21.1.1","21.1.2","21.1.3","21.2","21.2.1","21.2.2","21.2.3","21.2.4","21.3","21.3.1","22.0","22.0.1","22.0.2","22.0.3","22.0.4","22.1","22.1.1","22.1.2","22.1b1","22.2","22.2.1","22.2.2","22.3","22.3.1","23.0","23.0.1","23.1","23.1.1","23.1.2","23.2","23.2.1","23.3","23.3.1","23.3.2","24.0","24.1","24.1.1","24.1.2","24.1b1","24.1b2","24.2","24.3","24.3.1","25.0","25.0.1","25.1","25.1.1","25.2","25.3","26.0","26.0.1","6.0","6.0.1","6.0.2","6.0.3","6.0.4","6.0.5","6.0.6","6.0.7","6.0.8","6.1.0","6.1.1","7.0.0","7.0.1","7.0.2","7.0.3","7.1.0","7.1.1","7.1.2","8.0.0","8.0.1","8.0.2","8.0.3","8.1.0","8.1.1","8.1.2","9.0.0","9.0.1","9.0.2","9.0.3"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/04/GHSA-jp4c-xjxw-mgf9/GHSA-jp4c-xjxw-mgf9.json"}}],"references":[{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-6357"},{"type":"WEB","url":"https://github.com/pypa/pip/pull/13923"},{"type":"WEB","url":"https://github.com/pypa/pip/commit/b369bfc96cc524e00c267e1693290e6599c36bad"},{"type":"PACKAGE","url":"https://github.com/pypa/pip"},{"type":"WEB","url":"https://ichard26.github.io/blog/2026/04/whats-new-in-pip-26.1/#security-fixes"},{"type":"WEB","url":"http://www.openwall.com/lists/oss-security/2026/04/27/7"}],"database_specific":{"cwe_ids":["CWE-829"],"github_reviewed":true,"github_reviewed_at":"2026-05-05T22:05:46Z","nvd_published_at":"2026-04-27T15:16:20Z","severity":"MODERATE"},"severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:L/AC:L/AT:P/PR:H/UI:A/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N"}]}
