Executive Summary

This vulnerability in Wakapi before version 2.17.6 allows an attacker to take over user accounts by exploiting a shared cache key space. User lookups using User ID and API key were not properly separated, causing a cache key collision that could resolve lookups to unintended user contexts.

Detection Guidance

To detect this vulnerability, check if your Wakapi instance is running a version prior to 2.17.6. Use commands like 'curl -s https://your-wakapi-instance.com/api/version' or check the version in the admin panel. If the version is below 2.17.6, the system is vulnerable.

Impact Analysis

An attacker could gain unauthorized access to your Wakapi account without needing your credentials. This could lead to data exposure, account manipulation, or further attacks within the application. The vulnerability requires no privileges or user interaction to exploit.

Compliance Impact

This vulnerability could lead to unauthorized access to personal data, violating GDPR's data protection principles and HIPAA's security requirements for protected health information. Non-compliance may result in legal penalties and reputational damage.

Mitigation Strategies

Upgrade Wakapi to version 2.17.6 or later to address the cache key collision vulnerability. Ensure user caching is properly configured with distinct namespace prefixes for cache keys. No known workarounds exist besides upgrading.
