Security Issue with thinc package from pypi.org

[rakovskij-stanislav]

Hello! Found a security issue in your package in pypi:
https://pypi.org/project/thinc/

Affected versions of package:

• 6.10.4.dev0 (released Oct 14, 2018)

There's an unmet dependency on module "cupy-cuda10" if you will try to install these versions of sentry-sdk with extra-mode "cuda10".

ERROR: Could not find a version that satisfies the requirement cupy-cuda10>=5.0.0b4 (from thinc[cuda10]) (from versions: none)
ERROR: No matching distribution found for cupy-cuda10>=5.0.0b4

It happens because there is missed requirement in setup.py file:

...
            extras_require={
                'cuda': ['thinc_gpu_ops>=0.0.2,<0.1.0', 'cupy>=5.0.0b4'],
                'cuda80': ['thinc_gpu_ops>=0.0.2,<0.1.0', 'cupy-cuda80>=5.0.0b4'],
                'cuda90': ['thinc_gpu_ops>=0.0.2,<0.1.0', 'cupy-cuda90>=5.0.0b4'],
                'cthiuda91': ['thinc_gpu_ops>=0.0.2,<0.1.0', 'cupy-cuda91>=5.0.0b4'],
                'cuda92': ['thinc_gpu_ops>=0.0.2,<0.1.0', 'cupy-cuda92>=5.0.0b4'],
                'cuda10': ['thinc_gpu_ops>=0.0.2,<0.1.0', 'cupy-cuda10>=5.0.0b4'],
            },
...

It's dangerous because the intruder can create malicious package "cupy-cuda10" on pypi and:

• Make online guides how to use your package and abuse this malicious supply chain attack to compromise users.
• Infect automated CI/CD pipelines that uses old version of your package
• Infect other users by hardcoding those versions of package in opensource projects that use it

It's dangerous because usage of thinc, even outdated, is not something strange. Everyone likes hardcoded versions of packages, even in the era of protestware.

The best solution is to delete thinc 6.10.4.dev0 from pypi. Better to break dependencies in some old pipelines than compromise them. Furthermore this is a pre-release version of your package.
