The upload functionality for updating user profile does not properly validate the file content-type, allowing any authenticated user to bypass this security check by adding a valid signature (p.e. GIF89) and sending any invalid content-type. This could allow an authenticated attacker to upload HTML files with JS content that will be executed in the context of the domain.
