USN-8189-1: RapidJSON vulnerability

Publication date

20 April 2026

Overview

RapidJSON could be made to crash or run programs as an administrator if it opened a specially crafted file.


Packages

  • rapidjson - A fast JSON parser/generator for C++

Details

It was discovered that RapidJSON did not properly protect against integer
overflows in certain instances when parsing JSON text. A remote attacker
could possibly use this issue to craft a malicious JSON file, that when
read by RapidJSON, would lead to an elevation of privilege, resulting in
the potential disclosure of sensitive information.
