java-db-empty-password-mining
Read-only mining codemod for SonarSource rule java:S2115 — A secure password should be used when connecting to a database.
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 | java:S2115 |
| Type | Vulnerability |

What it detects
Database connection APIs invoked with an empty or blank password literal.
Sinks:
DriverManager.getConnection(url, user, "")(andDataSource/Hikari/pool variants)setPassword("")/password("")
Emission rule: Emits when the password argument is an empty or whitespace-only string literal.
