公告说明

Impact

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.

Patches

A fix for this issue has been released in Datasette 0.46.

Workarounds

You can fix this issue in a Datasette instance without upgrading by copying the 0.46 query.html template into a custom templates/ directory and running Datasette with the --template-dir=templates/ option.
