Summary

Rybbit before 2.7.0 contains a CORS misconfiguration vulnerability that allows attackers to bypass origin restrictions by reflecting any request origin in Access-Control-Allow-Origin responses while credentials are enabled. Attackers can issue credentialed cross-origin requests from any website to read analytics data, account information, and perform authenticated state-changing operations as the victim user.

Risk Assessment

The risk includes unauthorized data access and the ability to perform actions on behalf of the victim, which could lead to privacy and data integrity breaches.

Recommendation

Upgrade Rybbit to version 2.7.0 or later and configure CORS to restrict allowed origins.
