Server-Side Rendering (SSR)\nIn Angular applications that leverage Server-Side Rendering, an attacker can supply a malicious payload with an excessively long date format string. Processing this on the server causes high CPU usage and triggers a `JavaScript heap out of memory` crash, rendering the application unavailable to all users.\n\n#### 2.
