Hi,
The following vulnerability was published for libxstream-java.
CVE-2020-26259[0]:
| XStream is a Java library to serialize objects to XML and back again.
| In XStream before version 1.4.15, is vulnerable to an Arbitrary File
| Deletion on the local host when unmarshalling. The vulnerability may
| allow a remote attacker to delete arbitrary know files on the host as
| log as the executing process has sufficient rights only by
| manipulating the processed input stream. If you rely on XStream's
| default blacklist of the Security Framework, you will have to use at
| least version 1.4.15. The reported vulnerability does not exist
| running Java 15 or higher. No user is affected, who followed the
| recommendation to setup XStream's Security Framework with a whitelist!
| Anyone relying on XStream's default blacklist can immediately switch
| to a whilelist for the allowed types to avoid the vulnerability. Users
| of XStream 1.4.14 or below who still want to use XStream default
| blacklist can use a workaround described in more detailed in the
| referenced advisories.
If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
