CVE-2019-10747 : Vulnerability Insights and Analysis
Learn about CVE-2019-10747 affecting set-value function. Find out how attackers exploit Prototype Pollution, impact on systems, and mitigation steps to secure your applications.
Versions prior to 3.0.1 of the set-value function have a vulnerability to Prototype Pollution. This vulnerability arises due to the mixin-deep function being deceived into incorporating or altering attributes of Object.prototype through various payloads including the constructor, prototype, and proto.
Understanding CVE-2019-10747
set-value is vulnerable to Prototype Pollution in versions lower than 3.0.1. The function mixin-deep could be tricked into adding or modifying properties of Object.prototype using any of the constructor, prototype, and proto payloads.
What is CVE-2019-10747?
- Vulnerability in the set-value function allowing Prototype Pollution
- Exploitation through mixin-deep function manipulation
The Impact of CVE-2019-10747
- Attackers can modify or add properties to Object.prototype
- Potential for unauthorized access and data manipulation
