{"schema":"threatline.record/2","record":{"id":"CVE-2026-90466","aliases":[],"summary":"Apache Impala: Path traversal executes JARs outside trusted paths","details":"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.","categories":["Unclassified"],"product":"Apache Impala","vendor":"Apache Software Foundation","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-90466","source_modified_at":"2026-10-07T18:46:39.669Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"Apache Impala","vendor":"Apache Software Foundation","versions":[{"status":"affected","version":"4.5.2","lessThan":"4.5.3","versionType":"semver"}],"defaultStatus":"unaffected"}],"fixed_versions":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-90466","source_modified_at":"2026-10-07T18:46:39.669Z","fetched_at":"2026-10-23T18:48:36.087640Z","package":{"name":"Apache Impala","ecosystem":null},"version":"4.5.3","basis":"first unaffected version stated in the CVE record"}],"cvss":6.5,"severity":"Medium","kev":{"listed":false},"epss":{"probability":0.00504,"percentile":0.42209,"score_date":"2026-10-23"},"published_at":"2026-10-07T08:47:12.542Z","modified_at":"2026-10-07T18:46:39.669Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-90466","fetched_at":"2026-10-23T18:48:36.087640Z","source_modified_at":"2026-10-07T18:46:39.669Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-90466","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://lists.apache.org/thread.html/m7qbho4j1g4v7kx7pbk4z2n8p9nx6bqn","tags":["vendor-advisory"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CISA ADP","ssvc":{"exploitation":"none","automatable":"no","technical_impact":"partial","assessed_at":"2026-10-07T18:46:33.842491Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-07T18:46:39.669Z","content_hash":"244f7d88f5b76e513eb963c8f58556e27ff50874ddfe8f3b2397243a010115e5"}}
