Path traversal can't override the schema, but can result in loading a JAR that has been uploaded to a different location in that filesystem via Impala DDLs such as CREATE DATA SOURCE and CREATE TABLE. Path traversal can only be used if a trusted path exists, so this attack requires 'trusted_jar_paths' have a non-empty value configured by the Impala admin.\n\n\n\n\nUsers are recommended to upgrade to version 4.5.3, which fixes this issue.\n\n## Affected\n\n- `impala = 4.5.2`\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"sunlit","depthScore":36,"depthScoreParts":{"impact":35.8,"likelihood":0.1,"exploitation":0,"ransomware":0},"changes":[{"seq":217719,"id":"CVE-2026-90466","ts":1791406376441,"field":"cvss","old":null,"new":"6.5"},{"seq":217718,"id":"CVE-2026-90466","ts":1791406376441,"field":"severity","old":"none","new":"medium"}]}
