History

Shivani Bhardwaj 765a2dcb4e mqtt: add too_many_properties event and limit So far, the properties parsed across various different types of MQTT messages was unbounded and could be exploited. Add a limit of 255 on the maximum number of properties that any message type can store. Additionally, raise an event for too many properties indicating an anomaly in the network traffic. Ticket: 8839 (cherry picked from commit `df0e9f106b`)		2 months ago
