Executive Summary

This vulnerability is a missing permission check that allows low-privileged users with event access to extract specific information without needing order access. The exposed data includes attendee counts and total revenue for the event.

Detection Guidance

This vulnerability involves unauthorized access to event attendee counts and revenue data. To detect it, review application logs for unusual queries or access patterns to event-related endpoints, particularly those returning attendee numbers or financial data. Check for low-privileged user accounts accessing restricted event information without proper permissions.

Impact Analysis

Low-privileged users could gain unauthorized access to sensitive financial and attendance data, potentially leading to privacy breaches or misuse of event metrics.

Compliance Impact

This vulnerability allows low-privileged users to extract specific event information such as attendee numbers and revenue without proper access. This could potentially expose sensitive data, which may impact compliance with regulations like GDPR or HIPAA if such data includes personally identifiable information or protected health information.

Mitigation Strategies

Implement proper permission checks to restrict low-privileged users from accessing event information without appropriate access rights. Review and update user roles and permissions to ensure only authorized users can view sensitive event data.
