CVE-2024-21543

Publication date 13 December 2024

Last updated 18 March 2025

Ubuntu priority

Medium

Why this priority?

Versions of the package djoser before 2.3.0 are vulnerable to Authentication Bypass when the authenticate() function fails. This is because the system falls back to querying the database directly, granting access to users with valid credentials, and eventually bypassing custom authentication checks such as two-factor authentication, LDAP validations, or requirements from configured AUTHENTICATION_BACKENDS.
