{"id":"CVE-2021-39150","details":"XStream is a simple library to serialize objects to XML and back again. In affected versions this vulnerability may allow a remote attacker to request data from internal resources that are not publicly available only by manipulating the processed input stream with a Java runtime version 14 to 8. No user is affected, who followed the recommendation to setup XStream's security framework with a whitelist limited to the minimal required types. If you rely on XStream's default blacklist of the [Security Framework](https://x-stream.github.io/security.html#framework), you will have to use at least version 1.4.18.","aliases":["GHSA-cxfm-5m4g-x7xp"],"modified":"2026-03-20T11:43:26.830989Z","published":"2021-08-23T19:15:12.803Z","related":["GHSA-cxfm-5m4g-x7xp","MGASA-2021-0474","SUSE-SU-2021:3476-1","openSUSE-SU-2021:1401-1","openSUSE-SU-2021:3476-1","openSUSE-SU-2024:10592-1"],"references":[{"type":"ADVISORY","url":"https://lists.debian.org/debian-lts-announce/2021/09/msg00017.html"},{"type":"ADVISORY","url":"https://security.netapp.com/advisory/ntap-20210923-0003/"},{"type":"ADVISORY","url":"https://www.oracle.com/security-alerts/cpujul2022.html"},{"type":"ADVISORY","url":"https://github.com/x-stream/xstream/security/advisories/GHSA-cxfm-5m4g-x7xp"},{"type":"ADVISORY","url":"https://www.debian.org/security/2021/dsa-5004"},{"type":"FIX","url":"https://www.oracle.com/security-alerts/cpuapr2022.html"},{"type":"FIX","url":"https://www.oracle.com/security-alerts/cpujan2022.html"},{"type":"ARTICLE","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/PVPHZA7VW2RRSDCOIPP2W6O5ND254TU7/"},{"type":"ARTICLE","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/QGXIU3YDPG6OGTDHMBLAFN7BPBERXREB/"},{"type":"ARTICLE","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/22KVR6B5IZP3BGQ3HPWIO2FWWCKT3DHP/"},{"type":"EVIDENCE","url":"https://x-stream.github.io/CVE-2021-39150.html"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/x-stream/xstream","events":[{"introduced":"0"},{"fixed":"b9ad1c02724c2b1636a8794c8e1bcd630f46c0b3"}],"database_specific":{"versions":[{"introduced":"0"},{"fixed":"1.4.18"}]}}],"versions":["XSTREAM_1_4_10","XSTREAM_1_4_11","XSTREAM_1_4_11_1","XSTREAM_1_4_12","XSTREAM_1_4_13","XSTREAM_1_4_14","XSTREAM_1_4_15","XSTREAM_1_4_16","XSTREAM_1_4_17","XSTREAM_1_4_5","XSTREAM_1_4_9"],"database_specific":{"unresolved_ranges":[{"events":[{"introduced":"0"},{"last_affected":"33"}]},{"events":[{"introduced":"0"},{"last_affected":"34"}]},{"events":[{"introduced":"0"},{"last_affected":"35"}]},{"events":[{"introduced":"0"},{"last_affected":"9.0"}]},{"events":[{"introduced":"0"},{"last_affected":"10.0"}]},{"events":[{"introduced":"0"},{"last_affected":"11.0"}]},{"events":[{"introduced":"0"},{"last_affected":"12.2.1.4.0"}]},{"events":[{"introduced":"0"},{"last_affected":"11.3.2"}]},{"events":[{"introduced":"0"},{"last_affected":"11.3"}]},{"events":[{"introduced":"0"},{"last_affected":"12.0"}]},{"events":[{"introduced":"0"},{"last_affected":"1.9.0"}]},{"events":[{"introduced":"0"},{"last_affected":"1.10.0"}]},{"events":[{"introduced":"0"},{"last_affected":"1.14.0"}]},{"events":[{"introduced":"0"},{"last_affected":"7.3.4"}]},{"events":[{"introduced":"0"},{"last_affected":"7.3.5"}]},{"events":[{"introduced":"0"},{"last_affected":"7.4.0"}]},{"events":[{"introduced":"0"},{"last_affected":"7.4.1"}]},{"events":[{"introduced":"0"},{"last_affected":"7.4.2"}]},{"events":[{"introduced":"0"},{"last_affected":"16.0.6"}]},{"events":[{"introduced":"0"},{"last_affected":"17.0.4"}]},{"events":[{"introduced":"0"},{"last_affected":"18.0.3"}]},{"events":[{"introduced":"0"},{"last_affected":"19.0.2"}]},{"events":[{"introduced":"0"},{"last_affected":"20.0.1"}]},{"events":[{"introduced":"0"},{"last_affected":"4.2.0.2.0"}]},{"events":[{"introduced":"0"},{"last_affected":"4.2.0.3.0"}]},{"events":[{"introduced":"0"},{"last_affected":"4.3.0.1.0"}]},{"events":[{"introduced":"0"},{"last_affected":"4.3.0.6.0"}]},{"events":[{"introduced":"0"},{"last_affected":"4.4.0.0.0"}]},{"events":[{"introduced":"0"},{"last_affected":"4.4.0.2.0"}]},{"events":[{"introduced":"0"},{"last_affected":"4.4.0.3.0"}]},{"events":[{"introduced":"0"},{"last_affected":"6.0.0.1.1"}]},{"events":[{"introduced":"0"},{"last_affected":"12.2.1.3.0"}]},{"events":[{"introduced":"0"},{"last_affected":"12.2.1.4.0"}]}],"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2021-39150.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:C/C:H/I:H/A:H"}]}
