CVE-2026-42447Public exploit

HTML injection via unescaped APK library paths

Published Jul 14, 2026 · Updated Jul 14, 2026

HTML injection in Skylot JADX before 1.5.6 allows attackers to trigger requests from jadx-gui by inducing a user to open a crafted APK. SummaryNode.java passes arches and perArchCount values derived from APK .so path components to an HTML panel with builder.append() rather than escaping them. Exploitation requires the victim to open the APK and select Summary on macOS or GNU/Linux, enabling IP disclosure and requests to local services; Windows rejects the required entry names.
