CVE-2026-108147 Details
Description
An issue was discovered in Django 6.1 before 6.1.3, 6.0.4 before 6.0.10, and 5.2.13 before 5.2.19. `django.http.multipartparser.MultiPartParser` is subject to excessive memory consumption when processing multipart file uploads with base64 `Content-Transfer-Encoding`, which could be buffered entirely in memory before being passed to upload handlers. Earlier, unsupported Django series (such as 5.1.x, 5.0.x, and 4.2.x) were not evaluated and may also be affected. Django would like to thank Ignacy Kujawa for reporting this issue.
A memory exhaustion vulnerability has been identified in Django versions 6.1 prior to 6.1.3, 6.0.4 prior to 6.0.10, and 5.2.13 prior to 5.2.19. The issue arises in the `django.http.multipartparser.MultiPartParser` when handling multipart file uploads that use base64 `Content-Transfer-Encoding`. These uploads can be fully buffered in memory before being processed by upload handlers, leading to excessive memory consumption. While earlier unsupported Django series (such as 5.1.x, 5.0.x, and 4.2.x) were not evaluated, they may also be affected.
Users can upgrade to Django versions 6.1.3, 6.0.10, or 5.2.19 to address this vulnerability.
