The django.utils.html.strip_tags() function is vulnerable to a potential denial-of-service (slow performance) when processing inputs containing large sequences of incomplete HTML tags. The template filter striptags is also vulnerable, because it is built on top of strip_tags().\n\n## Affected packages\n\n- `django >= 4.2, < 4.2.21`\n- `django >= 5.1, < 5.1.9`\n- `django >= 5.2, < 5.2.1`\n\n## Remediation\n\nUpgrade to a patched release:\n\n- `django 4.2.21`\n- `django 5.1.9`\n- `django 5.2.1`","depth":"twilight","depthScore":44,"depthScoreParts":{"impact":29.2,"likelihood":2.7,"exploitation":12,"ransomware":0},"changes":[]}
