WordPress My Calendar Plugin Two Cross-Site Scripting Vulnerabilities


Description   Two vulnerabilities have been discovered in the My Calendar plugin for WordPress, which can be exploited by malicious people to conduct cross-site scripting attacks.
Input passed via the URL 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.
Successful exploitation requires that the "Display a jumpbox for changing month and year quickly?" option is enabled.
The vulnerabilities are confirmed in version 1.10.1. Prior versions may also be affected.
