What is CVE-2020-9482?

In the NiFi Registry versions ranging from 0.1.0 to 0.5.0, a significant security issue exists due to improper handling of authentication tokens. When users log out while using an authentication method other than Public Key Infrastructure (PKI), the system invalidates the token only on the client side. As a result, users' tokens remain valid on the server side for up to 12 hours post-logout. This enables unauthorized API requests using the stale token, posing a critical risk to data security and integrity.

Affected Version(s)

Apache NiFi Registry 0.1.0 to 0.5.0
