Cross-site scripting in Open Link before 1.0.5 allows remote attackers to execute JavaScript through crafted link content. The click path passes a link's href to the browser without protocol validation, allowing a javascript scheme to execute as code. The plugin must be enabled, and a user must open the crafted link inside CKEditor; execution occurs in a new browser tab.
