Description
This PR addresses a critical security vulnerability (CVE-2021-21341 and similar) in our XStream usage that could allow remote code execution through XML deserialization attacks. The current implementation lacked proper security restrictions on the XStream instance, allowing deserialization of arbitrary classes.
This vulnerability was also found in t-oster/VisiCut@3d6b930, corresponding to CVE-2021-39141 and fixed in this git commit.
