    Deserialization of Untrusted Data

    com.alibaba:fastjson is a fast JSON parser/generator for Java.

    Affected versions of this package are vulnerable to Deserialization of Untrusted Data. Fastjson uses a black and white list method to prevent deserialization vulnerabilities. As a result, when attackers continue to discover new deserialization gadgets, it is still possible to bypass the black and white list defense mechanism when autoType is closed, resulting in a remote command execution vulnerability.

    How to fix Deserialization of Untrusted Data?

    Upgrade com.alibaba:fastjson to version 1.2.69 or higher.
