Summary
OctoberCMS is a self-hosted content management system (CMS) based on the PHP programming language and Laravel web application framework. It supports MySQL, SQLite and PostgreSQL for the database back end and uses a flat file database for the front end structure. The October CMS covers a range of capabilities such as users, permissions, themes, and plugins, and is seen as a simpler alternative to WordPress.Description
OctoberCMS suffers from stored cross-site scripting vulnerability when a user with the ability to create an article could perform a stored XSS attack against any other users with the ability to create an article. This can lead to execute arbitrary HTML/JS code in a user's browser session in context of an affected site.Vendor
