An issue was discovered in Django 4.2 before 4.2.21, 5.1 before 5.1.9, and 5.2 before 5.2.1. 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().

The remote SUSE Linux SLES15 host has a package installed that is affected by a vulnerability as referenced in the SUSE- SU-2025:01523-1 advisory.

    - CVE-2025-32873: Fixed denial-of-service possibility in `strip_tags()` (bsc#1242210)

Tenable has extracted the preceding description block directly from the SUSE security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

The detected version of the Django Python package, Django, is 4.2.x prior to 4.2.21 or 5.1.x prior to 5.1.9 or 5.2.x prior to 5.2.1.

It is, therefore, affected by a denial of service vulnerability as disclosed in Django's May 7th 2025 security advisory. 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().

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

The remote SUSE Linux SLES15 / openSUSE 15 host has a package installed that is affected by a vulnerability as referenced in the SUSE-SU-2025:1523-1 advisory.

    - CVE-2025-32873: Fixed denial-of-service possibility in `strip_tags()` (bsc#1242210)

The remote Ubuntu 20.04 LTS / 22.04 LTS / 24.04 LTS / 24.10 / 25.04 host has a package installed that is affected by a vulnerability as referenced in the USN-7501-1 advisory.

    Elias Myllymki discovered that Django incorrectly handled stripping large sequences of incomplete HTML     tags. A remote attacker could possibly use this issue to cause Django to consume resources, leading to a     denial of service.

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
