CVE-2026-42447: CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in skylot jadx
jadx, a Dex to Java decompiler, has an HTML injection vulnerability in its GUI Summary tab in versions prior to 1.5.6. This occurs because unescaped data derived from APK file paths is inserted into an HTML panel, allowing a malicious APK to inject arbitrary HTML. The vulnerability 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 describes an HTML injection vulnerability (CWE-79) in jadx-gui prior to version 1.5.6. The SummaryNode.java component appends 'arches' and 'perArchCount' values derived from .so file path components inside an APK into an HTML panel without proper escaping. A maliciously crafted APK with HTML URL-encoded ZIP entry names can exploit this to render arbitrary HTML, potentially causing out-of-band network requests, victim IP disclosure, or interaction with local 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 analyzing a malicious APK. This can lead to out-of-band requests, disclosure of the victim's IP address, or interaction with locally exposed applications. The CVSS score is 3.6 (low severity), indicating limited impact primarily due to the requirement of local user interaction and limited confidentiality impact.
Mitigation Recommendations
Upgrade jadx to version 1.5.6 or later, where this vulnerability is fixed. There is no indication of alternative mitigations or temporary fixes. Users should avoid opening untrusted APK files with vulnerable versions of jadx.
