# CVE-2024-4068: Memory Exhaustion in braces

- Exploited (CISA KEV): no
- Published: 2024-05-13
- CVSS: 7.5 HIGH (v3.1)
- EPSS: 1.5% (74th percentile)
- CWE: CWE-1050

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.

"No public claim" means no vendor statement names this CVE; "Before feed history" means the CVE is older than the vendor feed. In both cases generic rules may still block it.
