Tóm tắt nhanh

CVE-2026-67214 là lỗ hổng mức CAO (CVSS 7.5) ảnh hưởng nanoid (nanoid project), nanoid.
Xác suất bị khai thác trong 30 ngày tới (EPSS): 0.33%, cao hơn 26.3% các lỗ hổng khác.
Cách xử lý: cập nhật lên 5.1.16, 3.3.16 hoặc mới hơn.

Gói / sản phẩm	Phiên bản bị ảnh hưởng	Phiên bản đã vá
nanoid nanoid_project	`≥ 4.0.0, < 5.1.16< 3.3.16`	`5.1.163.3.16`
nanoid npm	`≥ 4.0.0, < 5.1.16< 3.3.16`	`5.1.163.3.16`

Mô tả

nanoid (Nano ID) before 5.1.16 contains an infinite loop in the customAlphabet and nanoid functions of its non-secure module (nanoid/non-secure). When these functions are given a negative size, the loop counter is decremented from a negative value and never reaches its termination condition, spinning indefinitely and hanging the calling thread. An application that passes an unvalidated, attacker-controlled negative size to these functions is exposed to a denial-of-service condition.
