Maintainers, anything we can do here?
Perhaps you'd want to file a bug upstream and see what they say. Technically, I think it should be possible to patch the bundled wheels but that's a big meh.
I guess the affected versions are long gone, and in 20.26.3-r2 I'm finally removing bundled wheels (yay!).
Ok, I think we can thus call 20.26.3-r2 the fixed version. Seems highly complex to exploit, so let's call this done.
