CVE-2026-42447: CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in skylot jadx
jadx is a Dex to Java decompiler with a cross-site scripting (XSS) vulnerability in the jadx-gui Summary tab prior to version 1.5.6. The vulnerability arises because unescaped values derived from APK file path components are appended into an HTML panel, allowing a malicious APK to inject arbitrary HTML. This can lead to out-of-band requests, IP address disclosure, or interaction with local applications. The issue is fixed in version 1.5.6.
AI Analysis
Technical Summary
CVE-2026-42447 is a cross-site scripting vulnerability (CWE-79) in the jadx-gui Summary tab before version 1.5.6. The SummaryNode.java file appends 'arches' and 'perArchCount' values derived from .so file path components inside an APK into an HTML panel without proper escaping. A malicious APK with an HTML URL-encoded ZIP entry name can exploit this to inject arbitrary HTML, potentially causing out-of-band requests, victim IP disclosure, or interaction with locally exposed applications. The vulnerability is resolved in jadx version 1.5.6.
Potential Impact
The vulnerability allows an attacker to inject arbitrary HTML into the jadx-gui Summary tab when processing a malicious APK. This can lead to out-of-band network requests, disclosure of the victim's IP address, and interaction with local applications exposed on the victim's machine. The CVSS score is 3.6 (low severity), indicating limited impact primarily due to the requirement of local access and user interaction.
Mitigation Recommendations
Upgrade to jadx version 1.5.6 or later, where this vulnerability is fixed. No other specific mitigations are indicated. Patch status is confirmed by the vendor stating the issue is fixed in version 1.5.6.
