Description

Chartbrew is an open-source web application that can connect directly to databases and APIs and use the data to create charts. In version 4.9.0, the endpoint POST /user/invited does not validate any invite token, authentication header, or session. Any unauthenticated attacker can call this endpoint directly to create a fully active account and receive a valid JWT — even when the instance has existing users and signupRestricted is enabled. This bypass is distinct from the normal registration endpoint (POST /user) which enforces signupRestricted and sets active: false pending verification. This issue has been patched in version 5.0.0.

How this vulnerability can be exploited

This issue can be reached over the network, attack complexity is low, an attacker needs no privileges on the target. No user interaction is required. The scope is unchanged, so the impact stays within the vulnerable component. Rated impact: confidentiality low, integrity low, availability none.
