What is CVE-2023-22893?

Strapi versions up to 4.5.5 contain a vulnerability that allows remote attackers to bypass authentication mechanisms when using AWS Cognito as a login provider. This occurs due to insufficient verification of access or ID tokens generated during the OAuth process. By forging an ID token that utilizes the 'None' type algorithm, an attacker can impersonate any user authenticated through AWS Cognito, creating potential risks for data integrity and user security. It is crucial to update to a patched version to mitigate this risk.
