CyberRota Analysis

AI-Generated

Sylius versions prior to 1.12.25, 1.13.17, 1.14.20, 2.1.16, and 2.2.9 are vulnerable due to improper validation of the Host header in password-reset links, enabling unauthenticated attackers to redirect reset tokens to malicious domains. This flaw allows attackers to request password resets for administrator accounts and potentially seize control of those accounts. Organizations using affected versions should prioritize remediation to protect against unauthorized account access.

Original NVD Description

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.
