The `django.utils.html.urlize()` function was extremely slow to evaluate certain inputs due to catastrophic backtracking vulnerabilities in two regular expressions (only one regular expression for Django 1.8.x). The `urlize()` function is used to implement the urlize and urlizetrunc template filters, which were thus vulnerable.","affected":[{"package":{"name":"django","ecosystem":"PyPI","purl":"pkg:pypi/django"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"2.0a1"},{"fixed":"2.0.3"}]}],"versions":["2.0","2.0.1","2.0.2","2.0a1","2.0b1","2.0rc1"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2019/01/GHSA-r28v-mw67-m5p9/GHSA-r28v-mw67-m5p9.json"}},{"package":{"name":"django","ecosystem":"PyPI","purl":"pkg:pypi/django"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"1.11a1"},{"fixed":"1.11.11"}]}],"versions":["1.11","1.11.1","1.11.10","1.11.2","1.11.3","1.11.4","1.11.5","1.11.6","1.11.7","1.11.8","1.11.9","1.11a1","1.11b1","1.11rc1"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2019/01/GHSA-r28v-mw67-m5p9/GHSA-r28v-mw67-m5p9.json"}},{"package":{"name":"django","ecosystem":"PyPI","purl":"pkg:pypi/django"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"1.8a1"},{"fixed":"1.8.19"}]}],"versions":["1.8","1.8.1","1.8.10","1.8.11","1.8.12","1.8.13","1.8.14","1.8.15","1.8.16","1.8.17","1.8.18","1.8.2","1.8.3","1.8.4","1.8.5","1.8.6","1.8.7","1.8.8","1.8.9","1.8a1","1.8b1","1.8b2","1.8c1"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2019/01/GHSA-r28v-mw67-m5p9/GHSA-r28v-mw67-m5p9.json"}}],"references":[{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2018-7536"},{"type":"WEB","url":"https://github.com/django/django/commit/1ca63a66ef3163149ad822701273e8a1844192c2"},{"type":"WEB","url":"https://github.com/django/django/commit/abf89d729f210c692a50e0ad3f75fb6bec6fae16"},{"type":"WEB","url":"https://github.com/django/django/commit/e157315da3ae7005fa0683ffc9751dbeca7306c8"},{"type":"WEB","url":"https://access.redhat.com/errata/RHSA-2018:2927"},{"type":"WEB","url":"https://access.redhat.com/errata/RHSA-2019:0051"},{"type":"WEB","url":"https://access.redhat.com/errata/RHSA-2019:0082"},{"type":"WEB","url":"https://access.redhat.com/errata/RHSA-2019:0265"},{"type":"ADVISORY","url":"https://github.com/advisories/GHSA-r28v-mw67-m5p9"},{"type":"PACKAGE","url":"https://github.com/django/django"},{"type":"WEB","url":"https://github.com/pypa/advisory-database/tree/main/vulns/django/PYSEC-2018-5.yaml"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2018/03/msg00006.html"},{"type":"WEB","url":"https://usn.ubuntu.com/3591-1"},{"type":"WEB","url":"https://web.archive.org/web/20200227131019/http://www.securityfocus.com/bid/103361"},{"type":"WEB","url":"https://www.debian.org/security/2018/dsa-4161"},{"type":"WEB","url":"https://www.djangoproject.com/weblog/2018/mar/06/security-releases"}],"database_specific":{"cwe_ids":["CWE-185"],"github_reviewed":true,"github_reviewed_at":"2020-06-16T21:53:19Z","nvd_published_at":"2018-03-09T20:29:00Z","severity":"MODERATE"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L"},{"type":"CVSS_V4","score":"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"}]}
