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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":9.8},"cwes":["CWE-502"],"references":["https://discuss.lightbend.com/t/impact-of-cve-2022-36944-on-akka-cluster-akka-actor-akka-remote/10007/2","https://github.com/scala/scala-collection-compat/releases/tag/v2.9.0","https://github.com/scala/scala/pull/10118","https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/6ZOZVWY3X72FZZCCRAKRJYTQOJ6LUD6Z/","https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/L3WMKPFAMFQE3HJVRQ5KOJUTWG264SXI/"],"products":["fedoraproject:fedora","scala-lang:scala","scala-lang:scala-collection-compat"],"source":"nvd","synced_at":"2026-10-19T21:36:05.460296998+00:00"},"epss":{"cve":"CVE-2022-36944","score":0.10968,"percentile":0.95891,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-8qv5-68g4-248j","url":"https://osv.dev/vulnerability/GHSA-8qv5-68g4-248j","summary":"Scala subject to file deletion, code execution due to Java deserialization chain with LazyList object deserialization","modified":"2026-09-10T03:49:45.276399316Z","packages":[{"ecosystem":"Maven","name":"org.scala-lang:scala-library","purl":"pkg:maven/org.scala-lang/scala-library","ranges":[">=2.13.0 <2.13.9"],"fixed":["2.13.9"]}]}],"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).
