How to Fix CVE-2023-38503

To remediate this vulnerability, upgrade all affected Directus dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

directus fixed: 10.5.0
npm install directus@10.5.0
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release:

npm ls directus

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2023-38503, inspect your project dependencies using npm:

npm ls directus

Analyze the terminal output to locate any version of Directus in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 10.5.0), your application is affected.

Note: The npm ls directus command inspects dependencies declared in your package.json and lockfile; it does not perform automated runtime dynamic scanning.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-200: Exposure of Sensitive Information to an Unauthorized Actor, where the product exposes sensitive information to an actor that is not explicitly authorized to have access to that information. In Directus, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### Summary CWE-200: Exposure of Sensitive Information to an Unauthorized Actor Access to information you should not have access to when the permissions rely on `$CURRENT_USER` for filtering. ### Details The permission filters (i.e. `user_created IS $CURRENT_USER`) are not properly checked when using GraphQL subscription resulting in unauthorized users getting event on their subscription which they should not be receiving according to the permissions. This can be any collection but out-of-the box the `directus_users` collection is configured with such a permissions filter allowing you to get updates for other users when changes happen. An example: ```graphql subscription { directus_users_mutated { event data { id last_access last_page } } } ``` ### Patches https://github.com/directus/directus/pull/19155 ### Workarounds Disable GraphQL Subscriptions ### References
