Some vulnerabilities have been reported in Drupal, which can be exploited by malicious people to conduct cross-site scripting, cross-site request forgery, SQL injection, and script insertion attacks.

1) Certain input passed via taxonomy terms is not properly sanitised before being used. This can be exploited to insert arbitrary HTML and script code, which will be executed in a user's browser session in context of an affected site when a user selects a term and previews the node.

2) Certain input passed from OpenID providers is not properly sanitised before being returned to a user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.

These vulnerabilities reportedly affected version 6.x only.

3) The application allows users to perform certain actions via HTTP requests without performing any validity checks to verify the request. This can be exploited to e.g. delete OpenID identities or translation strings by enticing a logged-in user to visit a malicious site.

4) Certain input passed to numeric fields in the Schema API is not properly sanitised before being used in an SQL query. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code.

The vulnerabilities are reported in version 5.x and 6.x.
