Executive Summary

This vulnerability affects Payload, a free and open source headless content management system. In versions before 3.90.0 and canary versions before 4.0.0-canary.34, the server does not properly restrict updates to the password field in an authentication collection. This could allow unauthorized modifications to user passwords.

Detection Guidance

To detect this vulnerability, check the installed version of Payload CMS. If it is before 3.90.0 or a canary version before 4.0.0-canary.34, the system is vulnerable. Use commands like 'npm list payload' or check the version in the package.json file.

Impact Analysis

If exploited, this vulnerability could allow attackers to change user passwords without authorization. This may lead to unauthorized account access, data breaches, or loss of control over user accounts. Systems running vulnerable versions are at risk.

Compliance Impact

This vulnerability could lead to unauthorized access to sensitive data, violating confidentiality requirements in GDPR and HIPAA. Non-compliance may result in legal penalties, fines, or reputational damage due to data breaches.

Mitigation Strategies

Update Payload CMS to version 3.90.0 or later for stable releases, or to version 4.0.0-canary.34 or later for canary releases. This fixes the field-level access restriction issue on the password field.
