Description
Peppermint through 0.5.5 contains a missing authorization vulnerability that allows any authenticated user to create time entries and attachments as other users by supplying a user id in the request body. Attackers can send POST requests to /api/v1/time/new or /api/v1/storage/ticket/:id/upload/single to attach files and time records to any ticket under another user's identity.
