CVE-2026-54684: CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') in skylot jadx
jadx versions from 1.5.2 up to but not including 1.5.6 contain a path traversal vulnerability. A malicious .xapk file can cause jadx to write files outside the intended temporary directory, potentially planting a malicious JAR plugin. This plugin is then loaded and executed on the next run of jadx, leading to arbitrary code execution. The issue is fixed in version 1.5.6.
AI Analysis
Technical Summary
The vulnerability (CVE-2026-54684) in jadx, a Dex to Java decompiler, exists in versions 1.5.2 through 1.5.5. It allows a crafted .xapk archive to bypass intended directory restrictions due to improper pathname limitation (CWE-22). Specifically, XApkLoader resolves archive entry names directly with tmpDir.resolve(fileName) after a current working directory-based ZIP security check, enabling path traversal. When jadx is launched from a directory that is an ancestor of the config directory, this can lead to writing attacker-controlled JAR files into plugins/dropins. On subsequent runs, jadx loads these JARs via URLClassLoader and ServiceLoader, executing attacker-controlled plugin code. The vulnerability is addressed in version 1.5.6.
Potential Impact
Successful exploitation allows an attacker to execute arbitrary code within the context of jadx by planting malicious plugins. This can compromise the integrity and confidentiality of the host system where jadx is run. The CVSS 3.1 base score is 7.0 (High), reflecting local attack vector with high impact on confidentiality, integrity, and availability.
Mitigation Recommendations
This vulnerability is fixed in jadx version 1.5.6. Users should upgrade to version 1.5.6 or later to remediate this issue. No official patch or temporary workaround is indicated in the advisory. Until upgrading, avoid opening untrusted .xapk files with vulnerable versions of jadx.
