Recurring patterns

The bug types that recur here, drawn from past fixes, not open vulnerabilities.

Log4Shell: Five separate dependency bumps (2.15.0 through 2.17.2) show repeated exposure to Log4Shell; any future downgrade or transitive dependency reintroduces RCE via JNDI lookup.
XXE: Three distinct XML parsing paths (SchemaFactory, XPathFactory, Factory.parse) each needed individual hardening, indicating inconsistent application of secure processing flags across the codebase.
XML Signature Bypass: Enabling secureValidation on DOMValidateContext was required to prevent signature bypass; without it, malicious XML signatures can be accepted, undermining document integrity.
