NVD Description
Note: Versions mentioned in the description apply only to the upstream ruby3.3-oauth2 package and not the ruby3.3-oauth2 package as distributed by Wolfi.
See How to fix? for Wolfi relevant fixed versions and status.
OAuth2 is a Ruby wrapper for the OAuth 2.0 and 2.1 authorization frameworks, including OpenID Connect (OIDC). From 0.4.0 to 2.0.21, a protocol-relative redirect Location returned to OAuth2::Client#request overrides the request authority, so the bearer Authorization header is sent to an attacker-controlled host, leaking the credential. This issue is fixed in version 2.0.22.
