CVE-2022-36087 – OAuthLib vulnerable DoS when attacker provides malicious IPV6 URI

https://notcve.org/view.php?id=CVE-2022-36087

OAuthLib is an implementation of the OAuth request-signing logic for Python 3.6+. In OAuthLib versions 3.1.1 until 3.2.1, an attacker providing malicious redirect uri can cause denial of service. An attacker can also leverage usage of `uri_validate` functions depending where it is used. OAuthLib applications using OAuth2.0 provider support or use directly `uri_validate` are affected by this issue. Version 3.2.1 contains a patch. • https://github.com/oauthlib/oauthlib/blob/2b8a44855a51ad5a5b0c348a08c2564a2e197ea2/oauthlib/uri_validate.py https://github.com/oauthlib/oauthlib/blob/d4bafd9f1d0eba3766e933b1ac598cbbf37b8914/oauthlib/oauth2/rfc6749/grant_types/base.py#L232 https://github.com/oauthlib/oauthlib/commit/2e40b412c844ecc4673c3fa3f72181f228bdbacd https://github.com/oauthlib/oauthlib/releases/tag/v3.2.1 https://github.com/oauthlib/oauthlib/security/advisories/GHSA-3pgj-pg6c-r5p7 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/ • CWE-20: Improper Input Validation CWE-601: URL Redirection to Untrusted Site ('Open Redirect') •
