What this flaw is
CSRF tricks a logged-in user into unknowingly performing an action (e.g. changing settings or creating an account) when they visit a crafted page.
Combined with an administrator account, it lets an attacker quietly change the site configuration or add their own access.

What the CVSS 8 rating means in practice:
- The attack can be carried out remotely, over the internet.
