Version Details and Security Vulnerabilities

The package nanoid from 3.0.0, before 3.1.31, are vulnerable to Information Exposure via the valueOf() function which allows to reproduce the last id generated.

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 was found in the minimatch package. This flaw allows a Regular Expression Denial of Service (ReDoS) when calling the braceExpand function with specific arguments, resulting in a Denial of Service.
