High (8.7). EPSS 0.4% chance of exploitation in the next 30 days.

Grav API plugin versions before 1.0.20 build password reset links from the untrusted Host header in the forgot-password endpoint, allowing unauthenticated attackers to redirect reset tokens to attacker-controlled domains. Attackers can send password reset requests for any account with a malicious Host header, intercept the reset token from victim emails, and complete account takeover including super-admin accounts.
