Executive Summary

This vulnerability occurs in builds where PubSub and JSON are enabled. A specially crafted JSON message can exploit the decoder to write data beyond the bounds of a heap-allocated array before authentication takes place. This leads to reliable process crashes and memory corruption.

Impact Analysis

The vulnerability can cause the affected process to crash and corrupt memory, potentially leading to denial of service or unpredictable behavior in the application. Since the issue occurs before authentication, it may be exploited by unauthenticated attackers.
