Welcome to Depfu 👋

This is one of the first three pull requests with dependency updates we've sent your way. We tried to start with a few easy patch-level updates. Hopefully your tests will pass and you can merge this pull request without too much risk. This should give you an idea how Depfu works in general.

After you merge your first pull request, we'll send you a few more. We'll never open more than seven PRs at the same time so you're not getting overwhelmed with updates.

Let us know if you have any questions. Thanks so much for giving Depfu a try!

Security Advisories 🚨

🚨 Class-Name Injection

Parsedown before 1.7.2, when safe mode is used and HTML markup is disabled, might allow attackers to execute arbitrary JavaScript code if a script (already running on the affected page) executes the contents of any element with a specific class. This occurs because spaces are permitted in code block infostrings, which interferes with the intended behavior of a single class name beginning with the language- substring.

Release Notes

1.7.2

This is a security release and resolves an issue which would allow a user to add arbitrary classes to fenced code blocks. This might have security consequences, see #699 for more detail.

Does any of this look wrong? Please let us know.

👉 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/.
