CWE-79  (opens in a new tab)

How to fix?

There is no fixed version for RHEL:8 liborc.

NVD Description

Note: Versions mentioned in the description apply only to the upstream liborc package and not the liborc package as distributed by RHEL. See How to fix? for RHEL:8 relevant fixed versions and status.

There is a lack of XSS escaping in the Spark History Server prior to 3.5.8 which allows a malicious Spark job to generate arbitrary unescaped frontend code which could lead to a minimal privilege escalation in browser. Users are encouraged to upgrade to Spark 3.5.8 or later.

This CVE is marked as "low" since the path to exploit requires both relatively high permissions (ability to launch a Spark job) and requires tricking a user with higher permissions to log in and visit the Spark history web page.

Users are encouraged to upgrade their Spark history servers to Spark 3.5.8 or later.
