What is CVE-2022-42731?

The Django MFA2 library, prior to version 2.5.1 and 2.6.x versions before 2.6.1, is susceptible to a replay attack that enables an unauthorized actor to register additional devices on behalf of a user. The flaw arises as the device registration challenge fails to invalidate post-usage, potentially allowing exploitation of this weakness for malicious purposes.
