CVE-2021-39152: XStream <1.4.18 - Server-Side Request Forgery

日期: 2025-08-01 | 影响软件: XStream | POC: 已公开

漏洞描述

XStream before 1.4.18 is susceptible to server-side request forgery. An attacker can request data from internal resources that are not publicly available by manipulating the processed input stream with a Java runtime version 14 to 8. This makes it possible to obtain sensitive information, modify data, and/or execute unauthorized administrative operations in the context of the affected site.
