nanoid: nanoid: Denial of Service via negative size input in non-secure module functions

A flaw was found in nanoid Nano ID, a JavaScript library used for generating unique identifiers. This vulnerability allows an attacker to cause a Denial of Service DoS by providing a negative size input to the customAlphabet or nanoid functions within the library's non-secure module. When a...

nanoid: nanoid: Denial of Service via infinite loop in random ID generation

A flaw was found in nanoid Nano ID, a small, secure, and URL-friendly unique string ID generator. An attacker could exploit this vulnerability by providing a zero-size input to the customAlphabet or customRandom functions. This would cause an infinite loop, leading to a denial of service DoS...

Infinite loop

Overview Affected versions of this package are vulnerable to Infinite loop through the customRandom function in the customRandom implementation. An attacker can hang the calling thread by supplying a size of 0 to customRandom, which causes its ID generation loop to never reach a terminating...
