{"id":"CVE-2023-40570","aliases":["GHSA-7ch3-7pp7-7cpq","PYSEC-2023-154"],"url":"https://o3.security/vulnerability/CVE-2023-40570","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.","published":"2023-08-25T00:18:09.134Z","modified":"2026-08-12T03:51:22.024061607Z","cvss":{"score":5.3,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"PyPI","name":"datasette","fixedVersion":"1.0a4"}],"fix":{"url":"https://github.com/simonw/datasette/commit/01e0558825b8f7ec17d3b691aa072daf122fcc74","label":"simonw/datasette@01e0558"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/40xxx/CVE-2023-40570.json"},{"type":"ADVISORY","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":"FIX","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"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:22.024061607Z"}}
