Server-Side Request Forgery in calibreweb

Details

calibreweb prior to version 0.6.17 is vulnerable to server-side request forgery (SSRF). This is due to an incomplete fix for [CVE-2022-0339](https://github.com/advisories/GHSA-4w8p-x6g8-fv64). The blacklist does not check for `0.0.0.0`, which would result in a payload of `0.0.0.0` resolving to `localhost`.
