The OpenID Connect implementation, in the affected SFTPGo versions, allows authenticated users to brute force session cookies and thereby gain access to other users' data, since the cookies are generated predictably using the xid library and are therefore unique but not cryptographically secure.
This issue was fixed in version v2.6.4, where cookies are opaque and cryptographically secure strings.
