Technical details
A stored cross-site scripting (XSS) vulnerability exists in Bludit 4.0.0-beta's logo upload functionality. An authenticated Author-role user can upload a crafted SVG file containing embedded script tags as the site logo. The vulnerability occurs because the application fails to properly sanitize SVG uploads, allowing arbitrary JavaScript to be embedded and executed in the browser context of any user (including administrators) who loads the logo. The attack requires authentication and the Author role, but achieves stored payload persistence. Patches or remediation guidance from the vendor should be checked for availability.
