Vulnerability Details

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.
Mend Note: After conducting a further research, it was concluded that CVE-2024-4068 does not contain a high security risk that reflects the NVD score, but should be kept for users' awareness. Users of braces should follow the fix recommendation as noted.
