{"id":"GHSA-7ch3-7pp7-7cpq","summary":"Datasette 1.0 alpha series leaks names of databases and tables to unauthenticated users","details":"### Impact\n\nThis bug affects Datasette instances running a Datasette 1.0 alpha - 1.0a0, 1.0a1, 1.0a2 or 1.0a3 - in an online accessible location but with authentication enabled using a plugin such as [datasette-auth-passwords](https://datasette.io/plugins/datasette-auth-passwords).\n\nThe `/-/api` API explorer endpoint could reveal the names of both databases and tables - but not their contents - to an unauthenticated user.\n\n### Patches\n\nDatasette 1.0a4 has a fix for this issue.\n\n### Workarounds\n\nTo work around this issue, block all traffic to the `/-/api` endpoint. This can be done with a proxy such as Apache or NGINX, or by installing the [datasette-block](https://datasette.io/plugins/datasette-block) plugin and adding the following configuration to your `metadata.json` or `metadata.yml` file:\n\n```json\n{\n    \"plugins\": {\n        \"datasette-block\": {\n            \"prefixes\": [\"/-/api\"]\n        }\n    }\n}\n```\nThis will block access to the API explorer but will still allow access to the Datasette read or write JSON APIs, as those use different URL patterns within the Datasette `/database` hierarchy.","aliases":["CVE-2023-40570","PYSEC-2023-154"],"modified":"2026-06-09T13:30:22.435627390Z","published":"2023-08-22T18:06:46Z","database_specific":{"nvd_published_at":"2023-08-25T01:15:09Z","cwe_ids":["CWE-200","CWE-213"],"severity":"MODERATE","github_reviewed":true,"github_reviewed_at":"2023-08-22T18:06:46Z"},"references":[{"type":"WEB","url":"https://github.com/simonw/datasette/security/advisories/GHSA-7ch3-7pp7-7cpq"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-40570"},{"type":"WEB","url":"https://github.com/simonw/datasette/commit/01e0558825b8f7ec17d3b691aa072daf122fcc74"},{"type":"WEB","url":"https://github.com/pypa/advisory-database/tree/main/vulns/datasette/PYSEC-2023-154.yaml"},{"type":"PACKAGE","url":"https://github.com/simonw/datasette"}],"affected":[{"package":{"name":"datasette","ecosystem":"PyPI","purl":"pkg:pypi/datasette"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"1.0a0"},{"fixed":"1.0a4"}]}],"versions":["1.0a0","1.0a1","1.0a2","1.0a3"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2023/08/GHSA-7ch3-7pp7-7cpq/GHSA-7ch3-7pp7-7cpq.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N"}]}
