> 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.
