Predictable results in nanoid generation when given non-integer values

보통 4.3CVE-2024-55565 · GHSA-mwcw-c2x4-8c55 · Published 09/12/2024 · updated 17/06/2026

요약

Package	Affected versions	Patched versions
nanoid npm	`≥ 4.0.0, < 5.0.9< 3.3.8`	`5.0.93.3.8`

When nanoid is called with a fractional value, there were a number of undesirable effects:

in browser and non-secure, the code infinite loops on while (size--)
in node, the value of poolOffset becomes fractional, causing calls to nanoid to return zeroes until the pool is next filled
if the first call in node is a fractional argument, the initial buffer allocation fails with an error

Version 3.3.8 and 5.0.9 are fixed.

NVD description

nanoid (aka Nano ID) before 5.0.9 mishandles non-integer values. 3.3.8 is also a fixed version.
