nanoid: non-secure generators can loop indefinitely with negative size

CVE-2026-67214 / GHSA-28wg-ghj8-5hjv

More information

Details

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.

PR Summary

Low Risk
Lockfile-only dependency patch with no app code changes; reduces security risk rather than introducing new behavior.

Overview
Bumps the locked nanoid dependency from 5.1.7 to 5.1.16 in package-lock.json to address CVE-2026-67214 (GHSA-28wg-ghj8-5hjv).

The fix in upstream 5.1.16 stops an infinite loop in nanoid/non-secure when nanoid or customAlphabet receive a negative size, which could otherwise hang the process (DoS) if untrusted input reached those APIs. No application source files change in this PR—only the resolved lockfile version and integrity hash.
