Koillection through 1.8.4 Stored XSS via Datum File Attachment Uploads

Koillection through 1.8.4 contains a stored cross-site scripting vulnerability that allows authenticated users to upload HTML files as Datum file attachments lacking MIME restrictions. Attackers can upload HTML payloads via POST /api/data/{id}/file, served as text/html from public/uploads, executing JavaScript in victims' sessions to perform actions on their behalf.

An authenticated Server-Side Request Forgery (SSRF) in the custom scraper subsystem component of Benjamin Jonard Koillection v1.8.0 allows attackers to scan internal resources via supplying a crafted URL.
