The package com.alibaba:fastjson before 1.2.83 are vulnerable to Deserialization of Untrusted Data by bypassing the default autoType shutdown restrictions, which is possible under certain conditions. Exploiting this vulnerability allows attacking remote servers. Workaround: If upgrading is not possible, you can enable [safeMode](https://github.com/alibaba/fastjson/wiki/fastjson_safemode).
The product deserializes untrusted data without sufficiently ensuring that the resulting data will be valid.
