Description
Changes regex evaluator in
data-prepper-expressionanddata-prepper-plugins(key-value-processor,mutate-event-processors,mutate-string-processors,obfuscate-processor,split-event-processorandtranslate-processor) to Re2J to prevent adversarial regex pattern attacks.All other instances of regex still use default java regex library as they do not process user-input regex patterns.
