The Spaces OG submodule in the Spaces module 6.x-3.x before 6.x-3.7 for Drupal does not properly delete organic group group spaces content when using the option to move to a new group, which causes the content to be "orphaned" and allows remote authenticated users with the "access content" permission to obtain sensitive information via vectors involving a rebuild access for the site or content.

The Services module 6.x-3.x before 6.x-3.3 and 7.x-3.x before 7.x-3.3 for Drupal allows remote authenticated users with the "access user profiles" permission to access arbitrary users' emails via vectors related to the "user index method" and "the path to the user resource."
