October CMS through 1.0.428 does not prevent use of .htaccess in themes, which allows remote authenticated users to execute arbitrary PHP code by downloading a theme ZIP archive from /backend/cms/themes, and then uploading and importing a modified archive with two new files: a .php file and a .htaccess file. NOTE: the vendor says "I don't think [an attacker able to login to the system under an account that has access to manage/upload themes] is a threat model that we need to be considering.

Cross-Site Scripting exists in OctoberCMS 1.0.425 (aka Build 425), allowing a least privileged user to upload an SVG file containing malicious code as the Avatar for the profile. When this is opened by the Admin, it causes JavaScript execution in the context of the Admin account.
