How to Fix CVE-2022-24814

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: 9.7.0 
npm install directus@9.7.0
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-2022-24814, 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 9.7.0), 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-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting'), where the product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users. 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

### Impact Unauthorized JavaScript can be executed by inserting an iframe into the rich text html interface that links to a file uploaded HTML file that loads another uploaded JS file in its script tag. This satisfies the regular content security policy header, which in turn allows the file to run any arbitrary JS. ### Patches This was resolved in https://github.com/directus/directus/pull/12020 which is released in 9.7.0 ### Workarounds You can disable the live embed in the WYSIWYG by adding `{ "media_live_embeds": false }` to the _Options Overrides_ option of the Rich Text HTML interface. ### References https://github.com/directus/directus/pull/12020 ### For more information If you have any questions or comments about this advisory: * Open an issue in [directus/directus](https://github.com/directus/directus) * Email us at [security@directus.io](mailto:security@directus.io)
