XSS in Jadx Project
CVE-2026-42447
jadx is a Dex to Java decompiler. Prior to 1.5.6, jadx-gui is affected by an HTML injection vulnerability in the Summary tab because SummaryNode.java appends arches and perArchCount values derived from .so file path components inside an APK into an HTML panel without escaping. A malicious APK with an HTML URL-encoded ZIP entry name can force rendering of arbitrary HTML, perform out-of-band requests, disclose the victim IP address, or interact with locally exposed applications. This issue is fixed in version 1.5.6.
