The manipulation with an unknown input leads to a cross-site request forgery vulnerability. CWE is classifying the issue as CWE-352. The web application does not, or can not, sufficiently verify whether a well-formed, valid, consistent request was intentionally provided by the user who submitted the request. This is going to have an impact on integrity. The summary by CVE is:

The Form API in Drupal 6.x before 6.37 and 7.x before 7.39 does not properly validate the form token, which allows remote attackers to conduct CSRF attacks that upload files in a different user's account via vectors related to "file upload value callbacks."
