CVE-2020-25626 is a medium-severity flaw (CVSS 6.1) affecting django rest framework, ceph storage, debian linux. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

A flaw was found in Django REST Framework versions before 3.12.0 and before 3.11.2. When using the browseable API viewer, Django REST Framework fails to properly escape certain strings that can come from user input. This allows a user who can control those strings to inject malicious <script> tags, leading to a cross-site-scripting (XSS) vulnerability.
