{"id":"CVE-2018-17190","url":"https://www.cyber-defence.io/tools/cve/CVE-2018-17190","generatedAt":"2026-10-28T20:27:45.842Z","title":"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.","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.","published":"2018-11-19T14:29:01.000Z","lastModified":"2026-06-17T01:45:30.000Z","status":"Modified","sourceIdentifier":"security@apache.org","cvss":{"version":"3.0","score":9.8,"severity":"CRITICAL","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"},"cwe":[],"affected":["apache/spark"],"epss":{"score":0.08792,"percentile":0.95152,"date":"2026-10-27","history":[{"date":"2026-09-21","score":0.0689,"percentile":0.9385},{"date":"2026-09-22","score":0.08792,"percentile":0.94938}]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (8.79%).
