SCA: security update for briefcase (GHSA-r3r2-35v9-v238)

high Tenable Self-Hosted Container Security Plugin ID 439108

Description

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

 - Briefcase is a tool for converting a Python project into a standalone native application. Starting in
 version 0.3.0 and prior to version 0.3.26, if a developer uses Briefcase to produce an Windows MSI
 installer for a project, and that project is installed for All Users (i.e., per-machine scope), the
 installation process creates an directory that inherits all the permissions of the parent directory.
 Depending on the location chosen by the installing user, this may allow a low privilege but authenticated
 user to replace or modify the binaries installed by the application. If an administrator then runs the
 altered binary, the binary will run with elevated privileges. The problem is caused by the template used
 to generate the WXS file for Windows projects. It was fixed in the templates used in Briefcase 0.3.26,
 0.4.0, and 0.4.1. Re-running `briefcase create` on your Briefcase project will result in the updated
 templates being used. As a workaround, the patch can be added to any existing Briefcase .wxs file
 generated by Briefcase 0.3.24 or later. (CVE-2026-33430)

Solution

Update the briefcase library and its related packages to version 0.3.26 or later.
