java-nosql-injection-mining
Read-only mining codemod for SonarSource rule javasecurity:S5147 — NoSQL operations 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:S5147 |
| Type | Vulnerability |
| Severity | Blocker |
| Primary CWE | CWE-943 (Improper Neutralization of Special Elements in Data Query Logic) |
| Tags | cwe |
What it detects
MongoDB/NoSQL query sinks built from dynamic data.
Sinks:
MongoCollection.find / aggregate / findOne / where(collection-like receiver)Document.parse(...)/BasicDBObjectparsing
Emission rule: Only emits when a query argument is dynamic.
Metric: java-nosql-injection-mining
