Overview
Affected versions of this package are vulnerable to Server-side Request Forgery (SSRF) due to the use of HTTP redirects. An attacker can access internal services by leveraging HTTP redirects to bypass URL validation checks. This is only exploitable if the web-download, glance-download import methods, or the optional ovf_process image import plugin are enabled.
