CVE-2023-40570Network attack vector

Unauthenticated metadata disclosure via unchecked API explorer

Published Aug 25, 2023 · Updated Oct 2, 2024

Information disclosure in Simon Willison Datasette 1.0a0 through 1.0a3 allows remote attackers to read database and table names. The /-/api handler rendered the API explorer without first requiring view-instance permission and applied only narrower database and table visibility checks. Exposure requires an online instance protected by an authentication plugin; table contents are not disclosed.
