Summary This PR addresses a critical XXE (XML External Entity) vulnerability in the factory() method which creates an insecure SAXParserFactory without proper security configurations. Description The current implementation creates an XML parser that is vulnerable to XXE attacks. The parser is configured to validate XML documents and be namespace aware, but lacks critical security features that prevent malicious XML inputs from accessing local files, making network connections, or causing denial of service. References itsallcode/openfasttrace@3078109 https://nvd.nist.gov/vuln/detail/CVE-2018-12022
Summary This PR addresses a security vulnerability in the forName method where classes are loaded using the potentially untrusted thread context classloader instead of a specific trusted classloader. Description In untrusted environments, this classloader could be manipulated to load malicious classes. This change uses a specific trusted class's classloader instead, similar to the approach used in other secure parts of the codebase. References https://nvd.nist.gov/vuln/detail/cve-2022-22965
