Description
The download link for files uploaded through a form relied on a token that could be predicted. The file name in the request was also not verified in a way that resisted guessing. An unauthenticated attacker could use this to access files uploaded by other visitors. In addition, the token was shown in plain text in the text version of the notification email.
