Does this matter?

High impact if exploited, but EPSS currently rates exploitation as unlikely (1.41%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.

Description

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.
