Able to access private files when logged in with a different account/provider, which has not been granted access

I appear to be able to read, and overwrite files with a PUT, files in a private folder when logged in to a different account.

The example I found is editing https://andydavison.inrupt.net/private/test.jpg when logged in with https://ldp.demo-ess.inrupt.com/andydavison/. According to the ‘Your storage’ tab at https://andydavison.inrupt.net/, that private folder is not shared with anyone else, and indeed is inaccessible when logged out from both providers.

Reproduza o acesso relatado usando as duas URLs dos provedores, verificando tanto as leituras quanto as solicitações PUT para o arquivo privado test.jpg enquanto estiver conectado como a outra conta. Rastreie o caminho de autorização para o acesso entre provedores e verifique se uma conta sem permissão de compartilhamento não pode ler nem sobrescrever o arquivo privado.
