Some vulnerabilities have been reported in Horde and Horde Groupware, which can be exploited by malicious people to conduct cross-site scripting attacks and disclose potentially sensitive information.

1) Certain input passed to the horde/services/portal/cloud_search.php script is not properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.

2) Certain input passed to the framework/Image/Image.php script is not properly verified before being used to include files. This can be exploited to include arbitrary files from local resources.

The vulnerabilities are reported in Horde versions prior 3.2.4 and 3.3.3 and Horde Groupware prior to 1.1.5.
