Description
The vulnerability allows a remote user to execute arbitrary actions in the wiki.
The vulnerability exists due to cross-site scripting in the RSS macro HTML output when rendering feed item content from an attacker-controlled RSS feed with the content parameter set to true. A remote user can specify a malicious RSS feed to execute arbitrary actions in the wiki.
User interaction is required, and exploitation becomes particularly severe if a user with programming rights views the page.
