Authorization Bypass Through User-Controlled Key
In WESEEK GROWI before 3.5.0, the site-wide basic authentication can be bypassed by adding a URL parameter access_token (this is the parameter used by the API). No valid token is required since it is not validated by the backend. The website can then be browsed as if no basic authentication is required.
CWE-639 - Authorization Bypass Through User-Controlled Key
The system's authorization functionality does not prevent one user from gaining access to another user's data or record by modifying the key value identifying the data.
