This PR adds support for importing other modules within a plugin package.
This PR also replaces the use of
find_spec
fromimportlib.util
with a safer approach becausefind_spec
will implicitly import the parent module when the given name refers to a submodule.In particular, this behavior presents a security risk: if a bad actor manages to inject malicious code into the
__init__.py
file of the package, that code will execute as soon as the package is imported. Sincefind_spec
will import the package to resolve submodules, any malicious code in__init__.py
will run even before the sandbox has a chance to apply its restrictions. cc @beaugunderson
