# Exported Android component exposes a protected operation

An externally reachable activity, service or receiver performs work that its caller is not entitled to request.

**Candidate CWE:** [CWE-926](https://cwe.mitre.org/data/definitions/926.html)

## Test hypothesis

Record the intended app action, then repeat one harmless seeded operation from an ordinary companion app without the required permission. Compare with an explicitly authorized caller.

## Evidence required

Package/build/API level, resolved export and permission state, companion identity, exact intent, expected denial and protected result.

## Rule out false positives

Exported status or opening a public screen is insufficient. ADB-only access or privileged caller setup does not establish ordinary-app reachability.

## 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.
