CVE-2026-54048: Apache Impala

Medium severity, CVSS 5.3. EPSS: 0.5% chance of exploitation in the next 30 days.

Specifying tblproperties('avro.schema.url'=' http://...' ) or with a 'file:///' URI on a table in Impala 2.0.0 to 4.5.1 on all platforms allows an attacker to trigger a GET request to internal endpoints they may not have access to but that Impala does and the response my be exposed via parsing error messages. Users are recommended to upgrade to version 4.5.2, which fixes this issue.

Affected products

• Apache Impala: from 2.7.0, before 4.5.2 (fixed in 4.5.2)
