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/Capital2/GPT-Scanner/blob/f7a1eb7485126b737e9d5b8c817fe091c194ad44/requirements.txt lists MailGw-Temporary-Email 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/Capital2/GPT-Scanner 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 MailGw-Temporary-Email package on PyPI immediately or remove MailGw-Temporary-Email dependency from https://github.com/Capital2/GPT-Scanner/blob/f7a1eb7485126b737e9d5b8c817fe091c194ad44/requirements.txt to fix this vulnerability.
To automatically fix such issues in future, please install PackjGuard Github app [1].
Thanks!
