java-android-intent-redirection-mining
Read-only mining codemod for SonarSource rule javasecurity:S6384 — Components should not be vulnerable to intent redirection.
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.

What it detects
Android component launches whose Intent comes from an externally supplied value rather than a freshly constructed explicit Intent.
Sinks:
startActivity / startActivityForResult / startActivities / startService / startForegroundService / bindService / sendBroadcast / sendOrderedBroadcast / setResult
Emission rule: Emits only when the Intent argument is a variable, field, or method-call result (e.g. from getParcelableExtra). Freshly constructed new Intent(...) launches are skipped.
