CVE-2022-39227 Information

Description

python-jwt is a module for generating and verifying JSON Web Tokens. Versions prior to 3.3.4 are subject to Authentication Bypass by Spoofing resulting in identity spoofing session hijacking or authentication bypass. An attacker who obtains a JWT can arbitrarily forge its contents without knowing the secret key. Depending on the application this may for example enable the attacker to spoof other user’s identities hijack their sessions or bypass authentication. Users should upgrade to version 3.3.4. There are no known workarounds.
