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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","score":6.5},"cwes":["CWE-23"],"references":["https://lists.apache.org/thread.html/m7qbho4j1g4v7kx7pbk4z2n8p9nx6bqn","http://www.openwall.com/lists/oss-security/2026/10/07/20"],"products":["apache:impala"],"source":"nvd","synced_at":"2026-10-19T22:58:01.639778232+00:00"},"epss":{"cve":"CVE-2026-90466","score":0.00504,"percentile":0.42794,"date":"2026-10-25"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
