CVE-2026-93684: Apache Impala: Stored XSS in Impala query plans

[Michael Smith <michaelsmith () apache org>]

Severity: moderate 

Affected versions:

- Apache Impala 2.7.0 through 4.5.2

Description:

An SQL user using Impala up to and including version 4.5.2 with only SELECT permission can put JavaScript in a table 
alias and make it run in another user's browser when that user opens the query plan in Impala's Web UI. This is stored 
XSS (CWE-79). Users are recommended to upgrade to version 4.5.3.
