CVE-2026-67213

A flaw was found in nanoid (Nano ID), a small, secure, and URL-friendly unique string ID generator. An attacker could exploit this vulnerability by providing a zero-size input to the customAlphabet or customRandom functions. This would cause an infinite loop, leading to a denial of service (DoS) condition by hanging the application's calling thread.

7.5 (High)
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
