All applications which rely on serialization and do not isolate the code which deserializes objects were subject to this vulnerability.","published":"2018-01-18T18:29:00.000Z","lastModified":"2026-06-17T00:51:49.000Z","status":"Modified","sourceIdentifier":"cve@mitre.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":["CWE-502"],"affected":["apache/groovy","redhat/enterprise linux server"],"epss":{"score":0.17239,"percentile":0.97084,"date":"2026-10-27","history":[{"date":"2026-09-21","score":0.15852,"percentile":0.96786},{"date":"2026-09-22","score":0.17239,"percentile":0.96961}]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"urgent","text":"EPSS puts the probability of exploitation in the next 30 days at 17.2%, higher than 97% of all known CVEs.
