The system.temporary route in Drupal 8.x before 8.1.10 does not properly check for "Export configuration" permission, which allows remote authenticated users to bypass intended access restrictions and read a full config export via unspecified vectors.

The User module in Drupal 7.x before 7.44 allows remote authenticated users to gain privileges via vectors involving contributed or custom code that triggers a rebuild of the user profile form.

The Views module 7.x-3.x before 7.x-3.14 in Drupal 7.x and the Views module in Drupal 8.x before 8.1.3 might allow remote authenticated users to bypass intended access restrictions and obtain sensitive Statistics information via unspecified vectors.

PHP through 7.0.8 does not attempt to address RFC 3875 section 4.1.18 namespace conflicts and therefore does not protect applications from the presence of untrusted client data in the HTTP_PROXY environment variable, which might allow remote attackers to redirect an application's outbound HTTP traffic to an arbitrary proxy server via a crafted Proxy header in an HTTP request, as demonstrated by (1) an application that makes a getenv('HTTP_PROXY') call or (2) a CGI configuration of PHP, aka an "httpoxy" issue.

Open redirect vulnerability in the drupal_goto function in Drupal 6.x before 6.38, when used with PHP before 5.4.7, allows remote attackers to redirect users to arbitrary web sites and conduct phishing attacks via a double-encoded URL in the "destination" parameter.

Drupal 6.x before 6.38, 7.x before 7.43, and 8.x before 8.0.4 might allow remote attackers to conduct open redirect attacks by leveraging (1) custom code or (2) a form shown on a 404 error page, related to path manipulation.

The "have you forgotten your password" links in the User module in Drupal 7.x before 7.43 and 8.x before 8.0.4 allow remote attackers to obtain sensitive username information by leveraging a configuration that permits using an email address to login and a module that permits logging in.

CRLF injection vulnerability in the drupal_set_header function in Drupal 6.x before 6.38, when used with PHP before 5.1.2, allows remote attackers to inject arbitrary HTTP headers and conduct HTTP response splitting attacks by leveraging a module that allows user-submitted data to appear in HTTP headers.

The XML-RPC system in Drupal 6.x before 6.38 and 7.x before 7.43 might make it easier for remote attackers to conduct brute-force attacks via a large number of calls made at once to the same method.

The Form API in Drupal 6.x before 6.38 ignores access restrictions on submit buttons, which might allow remote attackers to bypass intended access restrictions by leveraging permission to submit a form with a button that has "#access" set to FALSE in the server-side form definition.
