Recurring patterns

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

XML External Entity (XXE): Insecure default parser configuration and failure to resolve the correct defusedexpat dependencies allowed remote attackers to trigger external entity resolution or XML entity expansion (XML bombs).

XML Injection: The unparse serialization workflow failed to properly sanitize element tags, attributes, and comments, allowing attackers to inject raw XML markup and modify structure via dictionary keys.
