Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
XXE: Secure SAXParserFactory configuration is essential to prevent external entity and DTD processing, which can lead to file disclosure or SSRF.
XXE: Entity resolution must be restricted to trusted classpath resources; otherwise arbitrary file/URL access via system IDs enables XXE and SSRF.
Reflected XSS: Unescaped titles in generated XDoc output can lead to reflected XSS when rendered in browsers.
