CWE-ID:
CWE-185 - Incorrect Regular Expression
Exploit availability: No

2) Uncontrolled Memory Allocation
EUVDB-ID: #VU92405
Risk: Medium
CVSSv3.1: 6.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2024-4068
CWE-ID:
CWE-789 - Uncontrolled Memory Allocation
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to NPM package `braces` fails to limit the number of characters it can handle, which could lead to Memory Exhaustion. A remote attacker can send "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.
