Description

This security bulletin contains information about 1 vulnerability.


1) Inefficient Algorithmic Complexity (CVE-ID: CVE-2026-13311)

CWE-ID: CWE-407 - Inefficient Algorithmic Complexity

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to cause a denial of service.

The vulnerability exists due to inefficient algorithmic complexity in the parse() function when parsing attacker-supplied strings. A remote attacker can submit a specially crafted input string to cause a denial of service.

The issue blocks the single-threaded Node.js event loop, and plain space-separated words are sufficient to trigger the vulnerable behavior.
