Technical details
The assemble-chunks function failed to scope the upload session lookup to the authenticated user's profile, relying only on the session ID for verification. An authenticated attacker who obtains a victim's live, completed upload-session UUID can assemble those chunks into their own file, team font, or project import, disclosing the uploaded bytes and deleting the victim's session. The fix adds profile-id parameter validation to assemble-chunks and all callers (assemble-file-media-object, create-font-variant, import-binfile) to match the security model already implemented in upload-chunk.
