java-server-side-template-injection-mining
Read-only mining codemod for SonarSource rule javasecurity:S5496 — Server-side templates should not be vulnerable to injection 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.
| Field | Value |
|---|---|
| Rule key | javasecurity:S5496 |
| Type | Vulnerability |
| Severity | Blocker |
| Primary CWE | CWE-94 (Code Injection) |
| Tags | cwe, python3 |
What it detects
Server-side template engine sinks built from dynamic templates/expressions.
Sinks:
SpelExpressionParser.parseExpression(...)Velocity.evaluate/VelocityEngine.evaluateStringTemplateEngine.process / createTemplate(Thymeleaf/Groovy)
Emission rule: Only emits when a template/expression argument is dynamic.
