Severity by source
AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N
Log access requires at minimum low-privilege read rights (PR:L); replaying the token is network-based (AV:N); full auth credential exposure yields high C/I; no availability impact.

Lifecycle Timeline
2DescriptionCVE.org
Logs contain replayable JWT tokens in Apache Ranger versions <= 2.8.0 Users are recommended to upgrade to version 2.9.0, which fixes this issue.
AnalysisAI
JWT tokens written to Apache Ranger logs in versions 2.8.0 and earlier remain replayable, allowing any party with read access to those logs to authenticate as legitimate users without knowing their credentials. The flaw (CWE-532) is particularly severe because Ranger controls data security policies across Hadoop ecosystems - impersonating a Ranger user can yield control over access policies for HDFS, Hive, HBase, and related services. …
