{"id":"CVE-2022-36944","url":"https://www.cyber-defence.io/tools/cve/CVE-2022-36944","generatedAt":"2026-11-04T23:59:59.319Z","title":"Scala 2.13.x before 2.13.9 has a Java deserialization chain in its JAR file.","description":"Scala 2.13.x before 2.13.9 has a Java deserialization chain in its JAR file. On its own, it cannot be exploited. There is only a risk in conjunction with Java object deserialization within an application. In such situations, it allows attackers to erase contents of arbitrary files, make network connections, or possibly run arbitrary code (specifically, Function0 functions) via a gadget chain.","published":"2022-09-23T18:15:11.000Z","lastModified":"2026-06-17T04:54:19.000Z","status":"Modified","sourceIdentifier":"cve@mitre.org","cvss":{"version":"3.1","score":9.8,"severity":"CRITICAL","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"},"cwe":["CWE-502"],"affected":["scala-lang/scala","scala-lang/scala-collection-compat","fedoraproject/fedora"],"epss":{"score":0.10968,"percentile":0.95897,"date":"2026-11-03","history":[{"date":"2026-09-20","score":0.10623,"percentile":0.95582}]},"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 11.0%, higher than 96% of all known CVEs.
