CVE-2024-55565

Описание

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

A flaw was found in nanoid. Affected versions of nanoid mishandles non-integer values. 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: when i is initialized to poolOffset, pool[i] & 63 -> undefined & 63 -> 0
• If the first call in node is a fractional argument, the initial buffer allocation fails with an error The highest impact of this issue system availability.
