Access bypass (file upload and execution) The resource/endpoint for uploading files does not properly sanitize the filename of uploaded files. This vulnerability is mitigated by the fact that the "File > Create" resource must be enabled and an attacker must have a role with the Services "Save file information" permission. .... Private fields information displayed Services does not check field_access when displaying entities so some private field information may be displayed. This vulnerability is only affecting sites using the field_permissions module configured to hide fields from anonymous users. -------- CVE IDENTIFIER(S) ISSUED -------------------------------------------- * /A CVE identifier [3] will be requested, and added upon issuance, in accordance with Drupal Security Team processes./ -------- VERSIONS AFFECTED --------------------------------------------------- Services 7.x-3.x versions prior to 7.x-3.12.
