GHSA-74r7-3mjm-jc5v
### Impact If the resolver parameter is passed, but the user does not exist, all failcounters of tokens in that resolver will be increased. ### Patches This, along with other issues, was fixed in eduMFA v2.9.1. ### Workarounds Limiting access to `/validate/check` to client applications (i.e. Shibboleth/FreeRADIUS) using an authorization policy with `api_key_required` or using e.g. the reverse proxy.
