{"id":"CVE-2026-90466","published":"2026-10-07T09:17:05.987","lastModified":"2026-10-13T14:27:04.630","description":"Path traversal of 'trusted_jar_paths' in Impala 4.5.2 allows an attacker-controlled JAR to be loaded via a relative path where the prefix matches a path specified in 'trusted_jar_paths'.\n\n\n\n\nThe startup flag 'trusted_jar_paths' references URIs for loading files from local or remote filesystems. 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.","cvssScore":6.5,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","cwes":["CWE-23"],"vendors":["apache"],"products":["impala"],"references":[{"url":"https://lists.apache.org/thread.html/m7qbho4j1g4v7kx7pbk4z2n8p9nx6bqn","tags":["Mailing List","Vendor Advisory"]},{"url":"http://www.openwall.com/lists/oss-security/2026/10/07/20","tags":["Mailing List","Third Party Advisory"]}],"exploitRefs":[],"hasPoc":false,"ai":null}
