CVE-2023-22893Public exploitNetwork attack vector

API-user impersonation via unverified Cognito ID tokens

Published Apr 19, 2023 · Updated Nov 7, 2025

Authentication bypass in Strapi 3.2.1 through 4.5.5 allows remote attackers to impersonate AWS Cognito-authenticated API users. The Cognito handler in the users-permissions providers registry decodes the supplied ID token and trusts its identity claims without verifying its signature against AWS. The AWS Cognito login provider must be enabled, and a forged unsigned token sent to its callback grants the victim's API-user access but not Strapi Admin Panel access.
