CVE-2022-39227

Description

A flaw was found in python-jwt, where it was subject to Authentication Bypass vulnerability by spoofing, resulting in identity spoofing, session hijacking, or authentication bypass. This flaw allows an attacker who obtains a JWT to arbitrarily forge its contents without knowing the secret key. Depending on the application, the attacker can spoof other users' identities, hijack their sessions, or bypass authentication.

Common Vulnerability Scoring System (CVSS) Score Details

Info alert: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).

The following CVSS metrics and score provided are preliminary and subject to review.
