Apache Impala: Stored XSS in Impala query plans

CISA KEV is observed exploitation evidence. FIRST EPSS is a dated prediction of exploitation in the next 30 days. Missing scores are unknown. This collector requests predictions only for explicit CVE aliases in the public NuGet archive; Microsoft release views retain their existing prediction scope.

No collected risk observation for these identifiers. This does not establish absence of exploitation or a zero probability.

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.
