Severity review proposal: "Receiver does not require permission" -> Major

[axel3rd]

Hello,

After some uses of sonar-android plugin, reviewing the level of this issue could be relevant:

Issue	Current severity	New severity	Justification
Receiver does not require permission	Minor	Major	In a company, the "receivers" are usually internal to an app or callable only from other applications of the company. They must not be discoverable and callable without restriction.

I can provide a PR if considered as relevant.
Best regards
