Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
XML External Entity (XXE): Insecure default configuration of XML parsers allows external entity expansion, which can lead to local file disclosure or Server-Side Request Forgery (SSRF) during the build/shading process. This is particularly dangerous if processing untrusted pom.xml files or shaded dependencies.
