However, if some untrusted code can register a malicious implementation with the thread context class loader first, then this implementation might be cached and re-used by Apache Santuario - XML Security for Java, leading to potential security flaws when validating signed documents, etc. The vulnerability affects Apache Santuario - XML Security for Java 2.0.x releases from 2.0.3 and all 2.1.x releases before 2.1.4.","published":"2019-08-23T21:15:11.490Z","modified":"2026-07-08T05:55:02.419597778Z","cvss":{"score":5.5,"severity":"MEDIUM","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Maven","name":"org.apache.santuario:xmlsec","fixedVersion":"2.1.4"}],"fix":null,"references":[{"type":"WEB","url":"https://lists.apache.org/thread.html/8e814b925bf580bc527d96ff51e72ffe5bdeaa4b8bf5b89498cab24c%40%3Cdev.santuario.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/edaa7edb9c58e5f5bd0c950f2b6232b62b15f5c44ad803e8728308ce%40%3Cdev.santuario.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/r107bffb06a5e27457fe9af7dfe3a233d0d36c6c2f5122f117eb7f626%40%3Ccommits.tomee.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/r1c07a561426ec5579073046ad7f4207cdcef452bb3100abaf908e0cd%40%3Ccommits.santuario.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/rcdc0da94fe21b26493eae47ca987a290bdf90c721a7a42491fdd41d4%40%3Ccommits.tomee.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/rf82be0a7c98cd3545e20817bb96ed05551ea0020acbaf9a469fef402%40%3Ccommits.tomee.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/rf958cea96236de8829940109ae07e870aa3d59235345421e4924ff03%40%3Ccommits.tomee.apache.org%3E"},{"type":"ADVISORY","url":"http://santuario.apache.org/secadv.data/CVE-2019-12400.asc?version=1&modificationDate=1566573083000&api=v2"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2020:0804"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2020:0805"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2020:0806"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2020:0811"},{"type":"ADVISORY","url":"https://security.netapp.com/advisory/ntap-20190910-0003/"},{"type":"FIX","url":"https://www.oracle.com/security-alerts/cpuoct2021.html"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2019-12400"},{"type":"WEB","url":"https://lists.apache.org/thread.html/8e814b925bf580bc527d96ff51e72ffe5bdeaa4b8bf5b89498cab24c@%3Cdev.santuario.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/edaa7edb9c58e5f5bd0c950f2b6232b62b15f5c44ad803e8728308ce@%3Cdev.santuario.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/r107bffb06a5e27457fe9af7dfe3a233d0d36c6c2f5122f117eb7f626@%3Ccommits.tomee.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/r1c07a561426ec5579073046ad7f4207cdcef452bb3100abaf908e0cd@%3Ccommits.santuario.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/rcdc0da94fe21b26493eae47ca987a290bdf90c721a7a42491fdd41d4@%3Ccommits.tomee.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/rf82be0a7c98cd3545e20817bb96ed05551ea0020acbaf9a469fef402@%3Ccommits.tomee.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/rf958cea96236de8829940109ae07e870aa3d59235345421e4924ff03@%3Ccommits.tomee.apache.org%3E"},{"type":"WEB","url":"https://security.netapp.com/advisory/ntap-20190910-0003"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-07-08T05:55:02.419597778Z"}}
