Last modified

CVE-2019-12400 is a medium-severity vulnerability rated 5.5/10 on the CVSS scale. In version 2.0.3 Apache Santuario XML Security for Java, a caching mechanism was introduced to speed up creating new XML documents using a static pool of DocumentBuilders. 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. EPSS estimates a 0.78% chance of exploitation in the next 30 days.
