Web Reference: May 6, 2025 · This bug, known as a "prototype pollution" flaw, lets attackers go way beyond just crashing your dashboard: they can run their own code on your server using specially-crafted HTTP requests, targeting Kibana’s machine learning and reporting features. JavaScript allows all Object attributes to be altered, including their magical attributes such as __proto__, constructor and prototype. An attacker manipulates these attributes to overwrite, or pollute, a JavaScript application object prototype of the base object by injecting other values. Now that we know where prototype pollution issues can occur, it is not enough to just pollute the properties on the prototype. We need to identify the areas that can be affected, meaning the places where the behavior changes after the properties are polluted.
