crafted XML documents. A remote attacker could possibly use this issue to
read arbitrary files. (CVE-2016-3674)

Zhihong Tian and Hui Lu found that XStream was vulnerable to remote code
execution. A remote attacker could run arbitrary shell commands by
manipulating the processed input stream. (CVE-2020-26217)

It was discovered that XStream was vulnerable to server-side forgery
attacks. A remote attacker could request data from internal resources
that are not publicly available only by manipulating the processed input
stream. (CVE-2020-26258)

It was discovered that XStream was vulnerable to arbitrary file deletion
on the local host. A remote attacker could use this to delete arbitrary
known files on the host as long as the executing process had sufficient
rights only by manipulating the processed input stream. (CVE-2020-26259)

It was discovered that XStream was vulnerable to denial of service,
arbitrary code execution, arbitrary file deletion and server-side forgery
attacks. A remote attacker could cause any of those issues by
manipulating the processed input stream. (CVE-2021-21341, CVE-2021-21342,
