I'm trying to find publicly available lists of risks which I can use in my own risk identification processes. Maybe risk taxonomies or just risk lists. Can anyone share such links?
If you're looking for risks, look at risk registers from previous projects. Those should be more relevant and accurate to whatever you're working on in your company. If they don't exist, try to get other PMs who worked on similar projects to list a couple for you and email them to you.
Ultimately, risks are very domain specific; risks in web development are not at all like risks in construction. So I don't think a public list exists, and if it did, I don't know how generic it would be.
The Risk Management Toolkit on the Mitre.org site is probably the best resource on the web for risk management. Look on the right under Taxonomies.
There's a smaller and useful list at the end of Tom Kendrick's "Identifying and Managing Project Risk".
But note that I agree with Ashes: you can use these for inspiration, but handle with care!
