Multiple vulnerabilities have been identified in Drupal, which may be exploited by attackers to execute arbitrary scripting code or bypass security restrictions.
The first issue is due to input validation errors in the XML parser and in the "aggregator", "profile", and "forum" modules, which could be exploited by attackers to cause arbitrary scripting code to be executed by the user's browser in the security context of an affected Web site.
The second issue is due to errors in various scripts that do not validate certain parameters supplied via HTTP GET or POST requests, which could be exploited by malicious people to conduct cross site request forgery attacks.
The third vulnerability is due to an error in the "filter_xss_bad_protocol()" function when handling form action attributes, which could be exploited by attackers to redirect a user's form submission to a malicious web site via a specially crafted link.
