🚨 Your version of puma has known security vulnerabilities 🚨

Advisory: CVE-2020-5247
Disclosed: February 27, 2020
URL: https://github.com/puma/puma/security/advisories/GHSA-84j7-475p-hp8v

HTTP Response Splitting vulnerability in puma

If an application using Puma allows untrusted input in a response header,
an attacker can use newline characters (i.e. CR, LF) to end the header and
inject malicious content, such as additional headers or an entirely new
response body. This vulnerability is known as HTTP Response Splitting.

While not an attack in itself, response splitting is a vector for several
other attacks, such as cross-site scripting (XSS).

🚨 We recommend to merge and deploy this update as soon as possible! 🚨

👉 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, Semaphore and Travis-CI 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/.
