Recurring patterns

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

XXE: The XML selector component relied on a parser configuration that allowed XML External Entity (XXE) resolution, potentially exposing the application to local file disclosure or server-side request forgery (SSRF) when processing untrusted XML documents. Developers must ensure that all XML parsing operations explicitly disable entity resolution.
