DescriptionGitHub Advisory

EverShop is a TypeScript-first eCommerce platform. Versions prior to 2.1.1 have a vulnerability in the "Forgot Password" functionality. When specifying a target email address, the API response returns the password reset token. This allows an attacker to take over the associated account. Version 2.1.1 fixes the issue.

Executive ViewAI

Why It Matters

A critical vulnerability in EverShop's password reset functionality could allow attackers to gain unauthorized access to customer accounts without valid credentials. This affects all organizations running EverShop versions prior to 2.1.1 and poses immediate risk to customer data, financial transactions, and regulatory compliance (GDPR, PCI-DSS).

Business Impact: Severe

Compensating Controls

Disable the 'Forgot Password' feature temporarily; implement Web Application Firewall (WAF) rules to block or rate-limit password reset endpoint requests; enforce network segmentation to restrict access to EverShop infrastructure; implement enhanced monitoring and alerting on authentication failure rates and account access anomalies; require multi-factor authentication (MFA) for all user accounts; review access logs for indicators of compromise.
