Version Details and Security Vulnerabilities

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

1. in browser and non-secure, the code infinite loops on while (size--)
2. in node, the value of poolOffset becomes fractional, causing calls to nanoid to return zeroes until the pool is next filled
3. 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.

A vulnerability exists in the 'min-document' package prior to version 2.19.0, stemming from improper handling of namespace operations in the removeAttributeNS method. By processing malicious input involving the proto property, an attacker can manipulate the prototype chain of JavaScript objects, leading to denial of service or arbitrary code execution. This issue arises from insufficient validation of attribute namespace removal operations, allowing unintended modification of critical object prototypes. The vulnerability remains unaddressed in the latest available version.
