Description

Snipe-IT is an IT asset/license management system. Prior to 8.5.0, Actionlog::logaction() stores the request User-Agent header and ReportsController::postActivityReport() writes that value to the Activity Report CSV without formula escaping, allowing a low-privileged authenticated user to store a formula-like User-Agent that may execute when a report viewer opens the exported CSV in spreadsheet software. This issue is fixed in version 8.5.0.
