CVE-2022-36087: Fedoraproject Fedora

Medium severity, CVSS 6.5. EPSS: 1.7% chance of exploitation in the next 30 days.

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. There are no known workarounds.

Affected products

• Fedoraproject Fedora: version 37 only
• Oauthlib Project Oauthlib: from 3.1.1, before 3.2.1 (fixed in 3.2.1)
