"value": "Scratch Addons is a WebExtension that supports both Chrome and Firefox. Scratch Addons before version 1.3.2 is vulnerable to DOM-based XSS.\n\nIf the victim visited a specific website, the More Links addon of the Scratch Addons extension used incorrect regular expression which caused the HTML-escaped values to be unescaped, leading to XSS.\n\nScratch Addons version 1.3.2 fixes the bug. The extension will be automatically updated by the browser.\n\nMore Links addon can be disabled via the option of the extension."
