Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Skylot Jadx是Skylot个人开发者开源的一个Dex到Java反编译器。 Skylot Jadx 1.5.2版本至1.5.5版本存在路径遍历漏洞，该漏洞源于XApkLoader在CWD-based ZIP安全检查后直接使用tmpDir.resolve(fileName)解析条目名称，可能导致恶意.xapk文件将攻击者控制的存档条目内容写入XAPK插件临时解包目录之外，当jadx从配置目录的祖先目录启动时，任意写入可在plugins/dropins中植入JAR，后续运行时攻击者插件代码被执行。

Vulnerability Title
jadx: XAPK archive entries with absolute paths can plant drop-in plugins and achieve code execution on the next jadx run
Source: CVE Program / CVE List V5
Vulnerability Description
jadx is a Dex to Java decompiler. From 1.5.2 to 1.5.5, a malicious .xapk file can cause jadx to write attacker-controlled archive entry contents outside the intended XAPK plugin temporary unpack directory because XApkLoader resolves each entry name directly with tmpDir.resolve(fileName) after a CWD-based ZIP security check. When jadx is launched from a directory that is an ancestor of the config directory, the arbitrary write can plant a JAR in plugins/dropins, and the next jadx run loads the JAR with URLClassLoader and ServiceLoader, executing attacker-controlled plugin code. This issue is fixed in version 1.5.6.
