Technical details
The PUT /app/:appId endpoint accepts an attacker-controlled icon storage path and mints 7-day signed URLs using the Supabase service-role client, which bypasses row-level security policies. The normalizeImagePath function performs only string formatting, not path validation, allowing authenticated attackers to request signed URLs for arbitrary paths in the private images bucket (user_id/filename, org/org_id/logo/filename, org/org_id/app_id/icon). Path enumeration is feasible because org IDs are visible to members and user/app IDs are often publicly known.
