# Nested intent redirects application authority

An exported entry point forwards attacker-supplied intent fields into a protected destination using the target application’s authority.

**Candidate CWE:** [CWE-441](https://cwe.mitre.org/data/definitions/441.html)

## Test hypothesis

Trace one legitimate forwarding path, then substitute a harmless lab destination while preserving other fields. Repeat from an ordinary app on the supported OS.

## Evidence required

Original and nested intents, controlled fields, caller/target identities, invoked capability and platform enforcement result.

## Rule out false positives

A forwarded public action is insufficient. Android 16 hardening can affect reachability; an older emulator or an opt-out test build cannot establish every release is affected.

## Report checklist

- [ ] Capture the affected version, configuration, identities, and object ownership.
- [ ] Preserve a valid baseline and a negative control.
- [ ] Reproduce the forbidden data access, action, or state change on controlled fixtures.
- [ ] Explain the intended security rule and why the observed behavior violates it.
- [ ] State prerequisites, uncertainty, cleanup, and the smallest demonstrated impact.
