CVE-2026-28276Network attack vector

Unauthenticated document disclosure via public upload URLs

Published Feb 26, 2026 · Updated Feb 26, 2026

Missing authorization in Morelitea Initiative before 0.32.2 allows remote attackers to read uploaded documents via direct file URLs. Initiative serves the /uploads/ directory publicly and performs no authentication, guild-membership, or document-permission check before returning a requested file. Knowledge or discovery of an upload URL is sufficient; the demonstrated consequence is unauthorized document disclosure without data modification or service interruption.
