Charlie Eriksen has discovered multiple vulnerabilities in the Mac Photo Gallery plugin for WordPress, which can be exploited by malicious people to conduct script insertion attacks.

Input passed via multiple parameters to two scripts 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 if malicious data is viewed.

List of affected scripts and parameters:
