CVE-2023-40570
Datasette 1.0 alpha series leaks names of databases and tables to unauthenticated users
CVE-2023-40570 is a medium vulnerability (CVSS 5.3) in Datasette, published August 22, 2023. No source lists public exploit code. EPSS puts the chance of exploitation in the next 30 days at 0.56%, the 46th percentile. Fixed in datasette 1.0a4.
Datasette is an open source multi-tool for exploring and publishing data. 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. Datasette 1.0a4 has a fix for this issue. 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. This issue is patched in version 1.0a4.

Datasette 1.0 alpha series leaks names of databases and tables to unauthenticated users
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:
{
"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.
