{"cve":"CVE-2018-17190","nvd":{"published":"2018-11-19T14:29:00.513","modified":"2026-06-17T01:45:30.497","status":"Modified","description":"In all versions of Apache Spark, its standalone resource manager accepts code to execute on a 'master' host, that then runs that code on 'worker' hosts. The master itself does not, by design, execute user code. A specially-crafted request to the master can, however, cause the master to execute code too. Note that this does not affect standalone clusters with authentication enabled. While the master host typically has less outbound access to other resources than a worker, the execution of code on the master is nevertheless unexpected.","cvss_v4":null,"cvss_v3":{"version":"3.0","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":9.8},"cwes":[],"references":["http://www.securityfocus.com/bid/105976","https://lists.apache.org/thread.html/341c3187f15cdb0d353261d2bfecf2324d56cb7db1339bfc7b30f6e5%40%3Cdev.spark.apache.org%3E","https://security.gentoo.org/glsa/201903-21","https://www.oracle.com/security-alerts/cpujul2020.html","http://www.securityfocus.com/bid/105976"],"products":["apache:spark"],"source":"nvd","synced_at":"2026-10-19T20:53:59.789560037+00:00"},"epss":{"cve":"CVE-2018-17190","score":0.08792,"percentile":0.95178,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-phg2-9c5g-m4q7","url":"https://osv.dev/vulnerability/GHSA-phg2-9c5g-m4q7","summary":"Remote Code Execution in spark-core","modified":"2024-12-02T05:46:07.781671Z","packages":[{"ecosystem":"Maven","name":"org.apache.spark:spark-core_2.11","purl":"pkg:maven/org.apache.spark/spark-core_2.11","ranges":["all versions"],"fixed":[]},{"ecosystem":"Maven","name":"org.apache.spark:spark-core_2.10","purl":"pkg:maven/org.apache.spark/spark-core_2.10","ranges":["all versions"],"fixed":[]}]}],"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).
