If `django.utils.text.Truncator`'s `chars()` and `words()` methods were passed the `html=True` argument, they were extremely slow to evaluate certain inputs due to a catastrophic backtracking vulnerability in a regular expression. The `chars()` and `words()` methods are used to implement the `truncatechars_htm`l and `truncatewords_html` template filters, which were thus vulnerable.","affected":[{"package":{"name":"django","ecosystem":"PyPI","purl":"pkg:pypi/django"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"1.11a1"},{"fixed":"1.11.23"}]}],"versions":["1.11","1.11.1","1.11.10","1.11.11","1.11.12","1.11.13","1.11.14","1.11.15","1.11.16","1.11.17","1.11.18","1.11.2","1.11.20","1.11.21","1.11.22","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/2019/08/GHSA-c4qh-4vgv-qc6g/GHSA-c4qh-4vgv-qc6g.json"}},{"package":{"name":"django","ecosystem":"PyPI","purl":"pkg:pypi/django"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"2.1a1"},{"fixed":"2.1.11"}]}],"versions":["2.1","2.1.1","2.1.10","2.1.2","2.1.3","2.1.4","2.1.5","2.1.7","2.1.8","2.1.9","2.1a1","2.1b1","2.1rc1"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2019/08/GHSA-c4qh-4vgv-qc6g/GHSA-c4qh-4vgv-qc6g.json"}},{"package":{"name":"django","ecosystem":"PyPI","purl":"pkg:pypi/django"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"2.2a1"},{"fixed":"2.2.4"}]}],"versions":["2.2","2.2.1","2.2.2","2.2.3","2.2a1","2.2b1","2.2rc1"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2019/08/GHSA-c4qh-4vgv-qc6g/GHSA-c4qh-4vgv-qc6g.json"}}],"references":[{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2019-14232"},{"type":"WEB","url":"https://www.openwall.com/lists/oss-security/2023/10/04/6"},{"type":"WEB","url":"https://www.djangoproject.com/weblog/2019/aug/01/security-releases"},{"type":"WEB","url":"https://www.debian.org/security/2019/dsa-4498"},{"type":"WEB","url":"https://security.netapp.com/advisory/ntap-20190828-0002"},{"type":"WEB","url":"https://security.gentoo.org/glsa/202004-17"},{"type":"WEB","url":"https://seclists.org/bugtraq/2019/Aug/15"},{"type":"WEB","url":"https://lists.opensuse.org/archives/list/security-announce@lists.opensuse.org/message/5XTP44JEOSNXRVW4JDZXA5XGMBDZLWSW"},{"type":"WEB","url":"https://lists.opensuse.org/archives/list/security-announce@lists.opensuse.org/message/3LGJSPCN3VEG2UJPYCUB6TU75JTIV2TQ"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/STVX7X7IDWAH5SKE6MBMY3TEI6ZODBTK"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/STVX7X7IDWAH5SKE6MBMY3TEI6ZODBTK"},{"type":"WEB","url":"https://groups.google.com/forum/#%21topic/django-announce/jIoju2-KLDs"},{"type":"WEB","url":"https://groups.google.com/forum/#!topic/django-announce/jIoju2-KLDs"},{"type":"WEB","url":"https://github.com/pypa/advisory-db/tree/main/vulns/django/PYSEC-2019-11.yaml"},{"type":"WEB","url":"https://github.com/pypa/advisory-database/tree/main/vulns/django/PYSEC-2019-11.yaml"},{"type":"PACKAGE","url":"https://github.com/django/django"},{"type":"ADVISORY","url":"https://github.com/advisories/GHSA-c4qh-4vgv-qc6g"},{"type":"WEB","url":"https://docs.djangoproject.com/en/dev/releases/security"},{"type":"WEB","url":"http://lists.opensuse.org/opensuse-security-announce/2019-08/msg00006.html"},{"type":"WEB","url":"http://lists.opensuse.org/opensuse-security-announce/2019-08/msg00025.html"},{"type":"WEB","url":"http://www.openwall.com/lists/oss-security/2023/10/04/6"},{"type":"WEB","url":"http://www.openwall.com/lists/oss-security/2024/03/04/1"}],"database_specific":{"cwe_ids":["CWE-400"],"github_reviewed":true,"github_reviewed_at":"2019-08-06T01:34:33Z","nvd_published_at":"2019-08-02T15:15:11Z","severity":"HIGH"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"},{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N"}]}
