CVE Severity Published▾ Status Exploitation Description
CVE-2025-70974 Critical 2026-01-09 Outside Waratek scope Exploited Fastjson before 1.2.48 mishandles autoType because, when an @type key is in a JSON document, and the value of that key is the name of a Java class, there may be calls to certain public methods of that class. Depending on the behavior of those methods, there may be JNDI injection with an attacker-supplied payload located elsewhere in that JSON document. This was exploited in the wild in 2023 through 2025. NOTE: this issue exists because of an incomplete fix for CVE-2017-18349. Also, a later bypass is covered by CVE-2022-25845.
CVE-2022-25845 Critical 2022-06-10 Mitigation candidate Proof of concept only 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).
CVE-2017-18349 Critical 2018-10-23 Outside Waratek scope Exploited parseObject in Fastjson before 1.2.25, as used in FastjsonEngine in Pippo 1.11.0 and other products, allows remote attackers to execute arbitrary code via a crafted JSON request, as demonstrated by a crafted rmi:// URI in the dataSourceName field of HTTP POST data to the Pippo /json URI, which is mishandled in AjaxApplication.java.
