datasette-graphql leaks details of the schema of private database files

GHSA-74hv-qjjq-h7g5

What to do

Vendor fix available. Upgrade each affected package to the fixed version on its release line (datasette-graphql 1.2), redeploy, then verify what is actually installed.

This page has no inventory attached, so it cannot say whether you are affected. A vendor fix is not proof that your deployment is fixed.

Source description

As published by the source; long descriptions are shortened.

Impact When running against a Datasette instance with private databases, datasette-graphql would expose the schema of those database tables - but not the table contents. Patches Patched in version 1.2. Workarounds This issue is only present if a Datasette instance that includes private databases and has the datasette-graphql plugin installed is available on the public internet. Uninstalling the datasette-graphql plugin or preventing public access to the instance can workaround this issue.

# Patch Next advisory brief: GHSA-74hv-qjjq-h7g5

Advisory: datasette-graphql leaks details of the schema of private database files
IDs: GHSA-74hv-qjjq-h7g5
Record: https://patchnext.com/advisories/ghsa-74hv-qjjq-h7g5 (revision 2, source checked 26 Oct 2026, 13:08 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Unrated
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: datasette-graphql 1.2. A vendor fix does not mean a deployment is fixed.

## Affected components
- PyPI datasette-graphql: affected < 1.2; fixed in 1.2

## Suggested inspection (read-only)
- `python -m pip show datasette-graphql`: prints the installed version. Run with the environment that serves production active.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on datasette-graphql.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.

## Sources
