Uncontrolled Resource Consumption in braces

CVE-2024-4068

  • braces
High
7.5/10

Summary

The NPM package "braces", versions prior to 3.0.3, fails to limit the number of characters it can handle, which could lead to Memory Exhaustion. In "lib/parse.js," if a malicious user sends "imbalanced braces" as input, the parsing will enter a loop, which will cause the program to start allocating heap memory without freeing it at any moment of the loop. Eventually, the JavaScript heap limit is reached, and the program will crash.

CWE-400 - Uncontrolled resource consumption

An uncontrolled resource allocation attack (also known as resource exhaustion attack) triggers unauthorized overconsumption of the limited resources in an application, such as memory, file system storage, database connection pool entries, and CPU. This may lead to denial of service for valid users and degradation of the application's functionality as well as that of the host operating system.
