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_html and truncatewords_html template filters, which were thus vulnerable.","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:N/A:H","score":7.5},"cwes":["CWE-400"],"references":["http://lists.opensuse.org/opensuse-security-announce/2019-08/msg00006.html","http://lists.opensuse.org/opensuse-security-announce/2019-08/msg00025.html","http://www.openwall.com/lists/oss-security/2023/10/04/6","http://www.openwall.com/lists/oss-security/2024/03/04/1","https://docs.djangoproject.com/en/dev/releases/security/"],"products":["djangoproject:django","opensuse:leap"],"source":"nvd","synced_at":"2026-10-19T20:58:11.797917892+00:00"},"epss":{"cve":"CVE-2019-14232","score":0.03531,"percentile":0.89257,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-c4qh-4vgv-qc6g","url":"https://osv.dev/vulnerability/GHSA-c4qh-4vgv-qc6g","summary":"Django Denial-of-service in django.utils.text.Truncator","modified":"2024-09-20T16:24:57.221275Z","packages":[{"ecosystem":"PyPI","name":"django","purl":"pkg:pypi/django","ranges":[">=1.11a1 <1.11.23"],"fixed":["1.11.23"]},{"ecosystem":"PyPI","name":"django","purl":"pkg:pypi/django","ranges":[">=2.1a1 <2.1.11"],"fixed":["2.1.11"]},{"ecosystem":"PyPI","name":"django","purl":"pkg:pypi/django","ranges":[">=2.2a1 <2.2.4"],"fixed":["2.2.4"]}]},{"id":"PYSEC-2019-11","url":"https://osv.dev/vulnerability/PYSEC-2019-11","summary":"","modified":"2023-11-08T04:01:09.281488Z","packages":[{"ecosystem":"PyPI","name":"django","purl":"pkg:pypi/django","ranges":[">=1.11 <1.11.23",">=2.1 <2.1.11",">=2.2 <2.2.4"],"fixed":["1.11.23","2.1.11","2.2.4"]}]}],"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).
