Requests is a HTTP library. Prior to 2.32.0, when making requests through a Requests Session, if the first request is made with verify=False to disable cert verification, all subsequent requests to the same host will continue to ignore cert verification regardless of changes to the value of verify. This behavior will continue for the lifecycle of the connection in the connection pool. This vulnerability is fixed in 2.32.0.
