CVE-2021-33203

Public on

Last Modified: UTC

Description

A flaw was found in django. Staff members could use the :mod:`~django.contrib.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. The highest threat from this vulnerability is to data confidentiality.

Common Vulnerability Scoring System (CVSS) Score Details

Important note

CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
