SCA: security update for org.apktool:apktool-lib (GHSA-m8mh-x359-vm8m)

high Tenable Cloud Security Plugin ID 440789

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Apktool is a tool for reverse engineering Android APK files. In versions 3.0.0 and 3.0.1, a path traversal
 vulnerability in `brut/androlib/res/decoder/ResFileDecoder.java` allows a maliciously crafted APK to write
 arbitrary files to the filesystem during standard decoding (`apktool d`). This is a security regression
 introduced in commit e10a045 (PR #4041, December 12, 2025), which removed the `BrutIO.sanitizePath()` call
 that previously prevented path traversal in resource file output paths. An attacker can embed `../`
 sequences in the `resources.arsc` Type String Pool to escape the output directory and write files to
 arbitrary locations, including `~/.ssh/config`, `~/.bashrc`, or Windows Startup folders, escalating to
 RCE. The fix in version 3.0.2 re-introduces `BrutIO.sanitizePath()` in `ResFileDecoder.java` before file
 write operations. (CVE-2026-39973)

Solution

Update the org.apktool:apktool-lib library and its related packages to version 3.0.2 or later.
