{"schema":"threatline.record/2","record":{"id":"CVE-2026-97395","aliases":[],"summary":"Apache Polaris: Allows authorized table writers to redirect server-side Iceberg FileIO requests to attacker-controlled endpoints using operation-scoped storage credentials","details":"Apache Polaris allows an authenticated principal with permission to create or update Iceberg table properties to set FileIO client settings such as s3.endpoint in table metadata.\n\n\nIn versions < 1.8.0, when Polaris performs server-side Iceberg operations, including commits and purges, it may use those settings to construct its (server-side) FileIO client. If the catalog storage configuration does not override the endpoint, Polaris can send storage requests to a host chosen by the table writer, using credentials scoped to the operation.\n\n\n\n\nThis can redirect server-side storage traffic and expose request authentication material to the chosen endpoint. Deployments are affected when table writers are not trusted to configure server-side storage endpoints.","categories":["Unclassified"],"product":"Apache Polaris","vendor":"Apache Software Foundation","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-97395","source_modified_at":"2026-10-01T16:13:41.152Z","fetched_at":"2026-10-23T18:52:38.922436Z","product":"Apache Polaris","vendor":"Apache Software Foundation","versions":[{"status":"affected","version":"0","lessThan":"1.8.0","versionType":"semver"}],"defaultStatus":"unaffected"}],"fixed_versions":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-97395","source_modified_at":"2026-10-01T16:13:41.152Z","fetched_at":"2026-10-23T18:52:38.922436Z","package":{"name":"Apache Polaris","ecosystem":null},"version":"1.8.0","basis":"first unaffected version stated in the CVE record"}],"cvss":8.1,"severity":"High","kev":{"listed":false},"epss":{"probability":0.00278,"percentile":0.19203,"score_date":"2026-10-23"},"published_at":"2026-09-29T13:57:32.682Z","modified_at":"2026-10-01T16:13:41.152Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-97395","fetched_at":"2026-10-23T18:52:38.922436Z","source_modified_at":"2026-10-01T16:13:41.152Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-97395","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/nrk339vtlkpsjw3mg4mqw52j0167wyph","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":"total","assessed_at":"2026-10-01T16:11:32.566325Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-01T16:13:41.152Z","content_hash":"ed0d1c228fdeee9b5a30e2ebafce9df30616cb1c7bfdf8d9811d0ef50cf95a33"}}
