> The recent CVE storm has proven that lookups are employed by users in many
> places where they shouldn't. In particular, lookups depending on
> {{LogEvent}}'s (e.g., {{ctx}}) are honey pots for attackers and there are
> safer ways to expose the very same information via more native constructs,
> e.g., MDC accessors in {{PatternLayout}} and {{JsonTemplateLayout}}. This
> story aims to enrich the lookup and certain layout documentations with such
> best practices.
