There is a MEDIUM severity vulnerability affecting the Python install manager.
Script alias entrypoints (e.g. pip.exe) generated by version 26.0 of the Python
install manager were very likely to have an empty search path, leading to
modules in the current working directory being able to override the intended
module and execute code as the user.
Version 26.1 is fixed. Versions prior to 26.0 are not impacted.
After installing the updated version, run "py install --refresh" to regenerate
existing aliases.
