All Attachments have a link that anyone can access, even without a ClickUp account. Site scraping bots can find all publicly accessible links. This is a huge security concern.
While the addresses are long and perhaps unlikely for someone to find by scraping, security by obscurity is not security at all. The Attachment address begins with my Workspace ID, so adversaries can even target my company's workspace specifically.
Attachments created at my company could very easily include confidential information. As an admin, I have no way of knowing what Attachments have been created, by whom, and who has access to them. Access to Attachments needs to be based on account authorization.
Note that Clips and Forms have the exact same issue.
This same issue was reported in 2021. It was marked as resolved when they implemented the "Private Attachments" features under Security & Permissions > Advanced Permissions. That is not Private at all. It's just temporarily public. Security by obscurity.
If you can stop people from seeing all my Tasks by requiring them to be logged in and have permissions, why can't that same basic security be applied to Attachments, Clips, and Forms in the same way?
