The HTML form for a read-only canned query includes the hidden CSRF token field added in #798 for writable canned queries (#698). This means that submitting those read-only forms exposes the CSRF token in the URL - for example on https://latest.datasette.io/fixtures/neighborhood_search submitting the form took me to: https://latest.datasette.io/fixtures/neighborhood_search?text=down&csrftoken=CSRFTOKEN-HERE This token could potentially leak to an attacker if the resulting page has a link to an external site on it and the user clicks the link, since the token would be exposed in the referral logs.
