Local Privilege Escalation in Windows

Impact

A PyInstaller built application, elevated as a privileged process, may be tricked by an unprivileged attacker into deleting files the unprivileged user does not otherwise have access to.

A user is affected if all the following are satisfied:

Patches

The vulnerability has been addressed in https://github.com/pyinstaller/pyinstaller/pull/7827 which corresponds to pyinstaller >= 5.13.1

Workarounds

Is there a way for users to fix or remediate the vulnerability without upgrading?

No workaround, although the attack complexity becomes much higher if the application is built with Python >= 3.8.0.
