  "details": "### Impact\n\nThe HTML form for a read-only canned query includes the hidden CSRF token field added in #798 for writable canned queries (#698).\n\nThis 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:\n\nhttps://latest.datasette.io/fixtures/neighborhood_search?text=down\u0026csrftoken=CSRFTOKEN-HERE\n\nThis 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.\n\n### Patches\n\nA fix for this issue has been released in Datasette 0.46.\n\n### Workarounds\n\nYou can fix this issue in a Datasette instance without upgrading by copying the [0.46 query.html template](https://raw.githubusercontent.com/simonw/datasette/0.46/datasette/templates/query.html) into a custom `templates/` directory and running Datasette with the `--template-dir=templates/` option.\n\n### References\n\nIssue 918 discusses this in details: https://github.com/simonw/datasette/issues/918\n\n### For more information\n\nContact swillison at gmail with any questions.",
