CVE-2024-23647
CVSS 3.1 Score 8.8 of 10 (high)
Details
Summary
CVE-2024-23647 is a vulnerability affecting the open-source Identity Provider, Authentik. The issue lies in the PKCE (Proof Key for Code Exchange) implementation, which allows an attacker to bypass the protection PKCE provides under certain conditions. Before versions 2023.8.7 and 2023.10.7, if the attacker removes the code_challenge parameter from the authorization request, Authentik will not perform the expected PKCE check. As a result, an attacker can execute CSRF attacks or code injection attacks that would normally be prevented by PKCE. Therefore, it is recommended that users upgrade to these fixed versions to mitigate this vulnerability.
