Description

Cloudreve is a self-hosted file management and sharing system. From 4.12.0 until 4.16.1, Cloudreve's OAuth access tokens are issued without the OAuth client_id claim, so the JWT verifier does not load token scopes into request context and RequiredScopes treats the request like non-scoped session authentication, allowing a low-scope OAuth access token to call APIs requiring higher scopes such as file, share, workflow, user setting, WebDAV account, and potentially admin scopes. This issue is fixed in version 4.16.1.
