Security Advisories 🚨

🚨 Multer vulnerable to Denial of Service via memory leaks from unclosed streams

Impact

Multer <2.0.0 is vulnerable to a resource exhaustion and memory leak issue due to improper stream handling. When the HTTP request stream emits an error, the internal busboy stream is not closed, violating Node.js stream safety guidance.

This leads to unclosed streams accumulating over time, consuming memory and file descriptors. Under sustained or repeated failure conditions, this can result in denial of service, requiring manual server restarts to recover. All users of Multer handling file uploads are potentially impacted.

Patches

Users should upgrade to 2.0.0

🚨 Multer vulnerable to Denial of Service from maliciously crafted requests

Impact

A vulnerability in Multer versions >=1.4.4-lts.1 allows an attacker to trigger a Denial of Service (DoS) by sending a malformed multi-part upload request. This request causes an unhandled exception, leading to a crash of the process.

Patches

Users should upgrade to 2.0.0

👉 No CI detected

You don't seem to have any Continuous Integration service set up!

Without a service that will test the Depfu branches and pull requests, we can't inform you if incoming updates actually work with your app. We think that this degrades the service we're trying to provide down to a point where it is more or less meaningless.

This is fine if you just want to give Depfu a quick try. If you want to really let Depfu help you keep your app up-to-date, we recommend setting up a CI system:

* [Circle CI](https://circleci.com), [Semaphore ](https://semaphoreci.com) and [Github Actions](https://docs.github.com/actions) are all excellent options. * If you use something like Jenkins, make sure that you're using the Github integration correctly so that it reports status data back to Github. * If you have already set up a CI for this repository, you might need to check your configuration. Make sure it will run on all new branches. If you don’t want it to run on every branch, you can whitelist branches starting with `depfu/`.
