What an attacker can do

Any attacker can hit `/authorize`, capture the server-generated state, finish the upstream OAuth flow with their own provider account, and then trick a victim into loading `.../callback?code=&state=`. Vendor/CNA’s CVSS 3.1 assessment (base score 5.9/10) rates confidentiality impact as high; integrity impact as low; availability impact as none. NVD’s CVSS 3.1 assessment (base score 8.8/10) rates confidentiality, integrity and availability impact as high.
