CVE-2024-47077Network attack vector

Cross-provider impersonation via mismatched token introspection

Published Sep 27, 2024 · Updated Sep 27, 2024

Incorrect authorization in authentik before 2024.6.5 and 2024.8.0-rc1 through 2024.8.2 allows remote authenticated users to cross provider boundaries. The token-introspection endpoint validates a proxy provider's client credentials separately from the supplied token instead of requiring the token to belong to that provider. Exploitation requires multiple proxy-provider applications with different trust domains or access controls and grants access to an application that the token holder is not authorized to use.
