- 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.
