NVD Description

Note: Versions mentioned in the description apply only to the upstream oauth2-proxy-fips package and not the oauth2-proxy-fips package as distributed by Minimos. See How to fix? for Minimos:latest relevant fixed versions and status.

When an HTTP server handler sends a 2xx response to an HTTP/1 CONNECT request and returns without hijacking the connection, the server improperly continues to read and serve requests from the connection. Since a 2xx response to an HTTP/1 CONNECT converts the connection into a tunnel, the server should not treat the connection as continuing to contain HTTP. The impact of this misbehavior is mostly limited to potential request smuggling, where an intermediate proxy considers the data on the connection to be tunneled and the server considers it to be HTTP.
