## Description

A stored cross-site scripting (Stored XSS) vulnerability in file preview in WeKan before 6.75 allows remote authenticated users to inject arbitrary web script or HTML via names of file attachments. Any user can obtain the privilege to rename within their own board (where they have BoardAdmin access), and renameAttachment does not block XSS payloads.

## What to do
