Django security releases issued: 3.2.4, 3.1.12, and 2.2.24

Posted by Carlton Gibson  on Tháng 6 2, 2021

In accordance with our security release policy, the Django team is issuing Django 3.2.4Django 3.1.12, and Django 2.2.24. These release addresses the security issue detailed below. We encourage all users of Django to upgrade as soon as possible.

CVE-2021-33203: Potential directory traversal via admindocs

Staff members could use the admindocs TemplateDetailView view to check the existence of arbitrary files. Additionally, if (and only if) the default admindocs templates have been customized by the developers to also expose the file contents, then not only the existence but also the file contents would have been exposed.

As a mitigation, path sanitation is now applied and only files within the template root directories can be loaded.

This issue has low severity, according to the Django security policy.

Thanks to Rasmus Lerchedahl Petersen and Rasmus Wriedt Larsen from the CodeQL Python team for the report.
