I've spent a lot of my career working in open source and I want to give back. Recently, I launched https://zeroquarry.com, which is a tool that helps you find 0-days in your software by through AI by tracing incoming requests down to the lowest level of implementation. The tool will do things like automatically suggest patches if you want or be more hands-off if you prefer. It will automatically produce POCs of the vulnerabilities for you to test.
I'm giving the tool away for free to any open source project. If you ping me directly (shane at the domain) with some details on what you're scanning, I'll increase credits or provide additional help.
