Mine servlet response writes fed by dynamic input that may enable reflected cross-site scripting (javasecurity:S5131); read-only metrics for security review
Read-only mining codemod for SonarSource rule javasecurity:S5131 — Endpoints should not be vulnerable to reflected cross-site scripting (XSS) attacks.
It scans Java source and emits metrics only; it never modifies code (return null).
Findings are high-signal review candidates surfaced by AST pattern matching — they are not proven vulnerabilities. A static mining pass cannot prove an end-to-end taint flow
from an untrusted source to the sink, so confirm data flow before remediating.
Emission rule: Only emits when the written argument is dynamic.
