Technical details

The vulnerability is a credential exposure issue where JWT bearer tokens are logged in plaintext within Apache Ranger's application logs in versions up to 2.8.0. These tokens can be replayed by an attacker who gains access to the logs (via file system access, log aggregation systems, or other log exposure vectors) to authenticate as the legitimate user without knowledge of their password. The attack requires either local or remote access to logs but does not require network access to actively exploit if logs are exfiltrated. The fix is available in Apache Ranger 2.9.0, which prevents JWT tokens from being logged.

Affected products
