Medium
6.5/10

Summary

OAuthLib is an implementation of the OAuth request-signing logic for Python 3.6+. In OAuthLib versions 3.1.1 through 3.2.1, an attacker providing a malicious redirect URI can cause a denial of service. An attacker can also leverage the usage of `uri_validate` functions depending on where it is used. OAuthLib applications using OAuth2.0 provider support or using directly `uri_validate` are affected by this issue. There are no known workarounds.
