What it detects
Reflected XSS: request value written straight to the servlet response: a xss check run by the textscan analyzer.
Evidence
The matching source path, line, and bounded code observation produced by the native rule.
Remediation
HTML-encode untrusted output (OWASP Encoder: Encode.forHtml(...)) or use a context-aware templating engine; never write a raw request parameter to the response.
Limitations
This check is limited to the applicability and evidence delivered by textscan. Review the evidence in context; a match is a finding input, while confidence and policy determine its disposition.
