Description

Checkmarx reported vulnerability with one of the dependent libraries (braces@3.0.2).

Category

CWE-400 | Uncontrolled resource consumption

Description

The NPM package "braces" 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.

Steps to reproduce

Run checkmarx scan on any nodejs project with pm2 dependency

Research direction

Start with the dependency tree in the issue and identify how pm2 brings in braces@3.0.2; review the reported behavior in braces' lib/parse.js and run a Checkmarx scan on the project. Done means the vulnerable dependency is no longer reported and the dependency resolution remains valid.
