CVE-2026-42447 Details
Description
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.
A prior version of the Jadx GUI (through 1.5.5) contains an HTML injection vulnerability in the Summary tab. This issue arises because the application improperly handles data from .so file paths within APKs, allowing for the injection of arbitrary HTML. An attacker can exploit this by crafting a malicious APK that includes a ZIP entry with an HTML URL-encoded name. When the APK is opened in Jadx, the injected HTML is rendered, potentially leading to out-of-band requests, IP address disclosure, or interaction with local applications.
Users can upgrade to Jadx GUI version 1.5.6 or later, where this vulnerability has been fixed.
