SCA: security update for org.apache.spark:spark-core_2.12, org.apache.spark:spark-core_2.13, pyspark (GHSA-9437-39hj-3c93)

medium Tenable Self-Hosted Container Security Plugin ID 473045

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - 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. (CVE-2026-32773)

Solution

Update the org.apache.spark:spark-core_2.12 library and its related packages to version 3.5.8 or later.
