What it is
Append tokens are public by design. Posts of several megabytes, screenshots written to disk and unlimited rows are possible.
What an attacker could do
Storage and drain time exhausted; real requests buried.
How: Public: the tokens are published on purpose.
Root cause
Rate and size limits are only in the browser.
What contributed
- The vault server's quotas are not known to this team.
What was not in place
Server-side quotas per token.
What would fix it
Quotas on the server; caps per drain; drop invalid rows before saving attachments.
