CVE-2026-67214— Andrey Sitnik Nano ID 资源管理错误漏洞

nanoid before 5.1.16 Infinite Loop via Negative Size in non-secure module

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.

不可达退出条件的循环(无限循环)

Andrey Sitnik Nano ID 资源管理错误漏洞

Andrey Sitnik nanoid是Andrey Sitnik个人开发者开源的一个用于 JavaScript 的小型、安全、URL 友好、唯一的字符串 ID 生成器。 Andrey Sitnik Nano ID 5.1.16之前版本存在资源管理错误漏洞，该漏洞源于customAlphabet和nanoid函数存在无限循环，当函数被赋予一个负数大小时，循环计数器从负值递减且永远不会达到终止条件，导致无限循环并挂起调用线程，可能造成拒绝服务。
