Issue
During my research, I found that this repo is vulnerable to attack due to deleted dependency from the public PyPI registry.
Details
Specifically, file https://github.com/ospc-org/ospc.org/blob/5edffcd5cf8bb6544afc1ed982636abe66e246e1/conda-requirements.txt lists xcalc as one of the dependencies. However, it has been deleted from public PyPI. As such, an external bad actor can claim that name and register a malicious package, which will be then installed with pip install command, resulting in arbitrary remote code execution.
Impact
Not only your apps/services using https://github.com/ospc-org/ospc.org repo code are vulnerable to this attack, but the users of your open-source Github repo could also fall victim.
Please manually register a placeholder xcalc package on PyPI immediately or remove xcalc dependency from https://github.com/ospc-org/ospc.org/blob/5edffcd5cf8bb6544afc1ed982636abe66e246e1/conda-requirements.txt to fix this vulnerability.
To automatically fix such issues in future, please install PackjGuard Github app [1].
