Detailed vulnerability description
The vulnerability allows a remote non-authenticated attacker to manipulate data.
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.
