Cloudreve: Path Traversal / Broken Access Control in Cloudreve WebDAV (`/dav`) — scoped DAV credential escapes its configured account root

Cloudreve is a self-hosted file management and sharing system. Prior to 4.16.1, a Cloudreve WebDAV account rooted at a configured folder can send paths such as /dav/%2e%2e/outside.txt because stripPrefix in pkg/webdav/webdav.go joins the decoded request suffix to the account root with fs.URI.JoinRaw without checking containment, allowing the scoped credential to read and list files outside the configured folder and writable credentials to create, overwrite, move, or delete them. This issue is reported as fixed in version 4.16.1.
