Official 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.
