Sylius versions before 1.12.25, 1.13.17, 1.14.20, 2.1.16, and 2.2.9 build administrator password-reset links using the request Host header without validation, allowing unauthenticated attackers to redirect reset tokens to attacker-controlled domains. Attackers can request password resets for known administrator email addresses with forged Host headers to intercept valid reset tokens and take over administrator accounts.
