Descriptions

An issue was discovered in Django 5.1 before 5.1.4, 5.0 before 5.0.10, and 4.2 before 4.2.17. The strip_tags() method and striptags template filter are subject to a potential denial-of-service attack via certain inputs containing large sequences of nested incomplete HTML entities.

A vulnerability was found in the Django Web Framework. The strip_tags() and stripbtags template filter may be vulnerable to a potential denial of service (DoS) in cases of a large sequence of nested incomplete HTML entities.

jiangniao discovered that Django incorrectly handled the API to strip tags. A remote attacker could possibly use this issue to cause Django to consume resources, leading to a denial of service. Seokchan Yoon discovered that Django incorrectly handled HasKey lookups when using Oracle. A remote attacker could possibly use this issue to inject arbitrary SQL code. This issue only affected Ubuntu 24.04 LTS and Ubuntu 24.10.
