Attack-Flow Graph

Executive Summary

Payload CMS versions before 3.90.0 and canary versions before 4.0.0-canary.34 have an issue where querying a readable collection with a relationship to another collection can expose information about related documents that should be protected by access.read constraints.

Detection Guidance

This vulnerability involves information exposure through collection relationships in Payload CMS versions before 3.90.0 and canary versions before 4.0.0-canary.34. To detect it, check your Payload CMS version using commands like 'npm list payloadcms' or 'grep payloadcms package.json'. If the version is below the patched versions, the system is vulnerable.

Impact Analysis

This vulnerability could allow unauthorized access to sensitive information in related documents that should be restricted. Attackers might exploit it to read data they are not permitted to access.

Compliance Impact

This vulnerability could lead to unauthorized data exposure, potentially violating privacy regulations like GDPR or HIPAA by allowing access to protected information without proper authorization.

Mitigation Strategies

Upgrade Payload CMS to version 3.90.0 or later for the stable release, or to version 4.0.0-canary.34 or later for the canary release to address the vulnerability.
