GHSA-7ch3-7pp7-7cpq Datasette 1.0 alpha series leaks names of databases and tables to unauthenticated users

• PyPI datasette: >= 1.0a0, < 1.0a4 → fixed in 1.0a4

Impact This 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. The `/-/api` API explorer endpoint could reveal the names of both databases and tables - but not their contents - to an unauthenticated user. Patches Datasette 1.0a4 has a fix for this issue. Workarounds To 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 plugin and adding the following configuration to your `metadata.json` or `metadata.yml` file: ```json { "plugins": { "datasette-block": { "prefixes": ["/-/api"] } } } ``` This 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.
