{"id":"CVE-2021-21350","details":"XStream is a Java library to serialize objects to XML and back again. In XStream before version 1.4.16, there is a vulnerability which may allow a remote attacker to execute arbitrary code only by manipulating the processed input stream. 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, you will have to use at least version 1.4.16.","aliases":["BIT-activemq-2021-21350","GHSA-43gc-mjxg-gvrq"],"modified":"2026-02-24T01:21:14.297531Z","published":"2021-03-23T00:15:13.273Z","related":["GHSA-43gc-mjxg-gvrq","MGASA-2021-0370","SUSE-SU-2021:1840-1","SUSE-SU-2021:1840-2","openSUSE-SU-2021:0832-1","openSUSE-SU-2021:1840-1","openSUSE-SU-2024:10592-1"],"references":[{"type":"WEB","url":"https://x-stream.github.io/security.html#workaround"},{"type":"ADVISORY","url":"http://x-stream.github.io/changes.html#1.4.16"},{"type":"ADVISORY","url":"https://github.com/x-stream/xstream/security/advisories/GHSA-43gc-mjxg-gvrq"},{"type":"ADVISORY","url":"https://lists.apache.org/thread.html/r8244fd0831db894d5e89911ded9c72196d395a90ae655414d23ed0dd%40%3Cusers.activemq.apache.org%3E"},{"type":"ADVISORY","url":"https://lists.apache.org/thread.html/r9ac71b047767205aa22e3a08cb33f3e0586de6b2fac48b425c6e16b0%40%3Cdev.jmeter.apache.org%3E"},{"type":"ADVISORY","url":"https://lists.debian.org/debian-lts-announce/2021/04/msg00002.html"},{"type":"ADVISORY","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/22KVR6B5IZP3BGQ3HPWIO2FWWCKT3DHP/"},{"type":"ADVISORY","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/PVPHZA7VW2RRSDCOIPP2W6O5ND254TU7/"},{"type":"ADVISORY","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/QGXIU3YDPG6OGTDHMBLAFN7BPBERXREB/"},{"type":"ADVISORY","url":"https://security.netapp.com/advisory/ntap-20210430-0002/"},{"type":"ADVISORY","url":"https://www.debian.org/security/2021/dsa-5004"},{"type":"ADVISORY","url":"https://www.oracle.com//security-alerts/cpujul2021.html"},{"type":"ADVISORY","url":"https://www.oracle.com/security-alerts/cpujan2022.html"},{"type":"ADVISORY","url":"https://www.oracle.com/security-alerts/cpuoct2021.html"},{"type":"ADVISORY","url":"https://x-stream.github.io/CVE-2021-21350.html"},{"type":"ADVISORY","url":"https://x-stream.github.io/security.html#workaround"},{"type":"REPORT","url":"https://lists.apache.org/thread.html/r8244fd0831db894d5e89911ded9c72196d395a90ae655414d23ed0dd%40%3Cusers.activemq.apache.org%3E"},{"type":"REPORT","url":"https://lists.apache.org/thread.html/r9ac71b047767205aa22e3a08cb33f3e0586de6b2fac48b425c6e16b0%40%3Cdev.jmeter.apache.org%3E"},{"type":"FIX","url":"https://www.oracle.com/security-alerts/cpujan2022.html"},{"type":"ARTICLE","url":"https://lists.apache.org/thread.html/r8244fd0831db894d5e89911ded9c72196d395a90ae655414d23ed0dd%40%3Cusers.activemq.apache.org%3E"},{"type":"ARTICLE","url":"https://lists.apache.org/thread.html/r9ac71b047767205aa22e3a08cb33f3e0586de6b2fac48b425c6e16b0%40%3Cdev.jmeter.apache.org%3E"},{"type":"ARTICLE","url":"https://lists.debian.org/debian-lts-announce/2021/04/msg00002.html"},{"type":"ARTICLE","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/22KVR6B5IZP3BGQ3HPWIO2FWWCKT3DHP/"},{"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://www.debian.org/security/2021/dsa-5004"},{"type":"EVIDENCE","url":"https://x-stream.github.io/CVE-2021-21350.html"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/x-stream/xstream","events":[{"introduced":"0"},{"fixed":"3dd9cc610199802e4f13bd49b02a9f99adaba145"}]}],"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_5","XSTREAM_1_4_9"],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2021-21350.json"}}],"schema_version":"1.7.3","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"}]}
