Denial Of Service (DoS)

nanoid is vulnerable to Denial Of Service. The vulnerability is due to an infinite loop in customAlphabet and customRandom when configured with a size of 0, allowing attacker-controlled input to hang the calling thread and cause application unavailability...

GHSA-2V37-7H3G-55P8 nanoid: custom generators can loop indefinitely when size is zero

nanoid Nano ID before 5.1.6 contains an infinite loop in the customAlphabet and customRandom functions. When these functions are configured with a size of 0, the internal generation loop never satisfies its exit condition and spins indefinitely, hanging the calling thread. An application that...

GHSA-28WG-GHJ8-5HJV nanoid: non-secure generators can loop indefinitely with negative size

nanoid Nano ID before 5.1.16 contains an infinite loop in the customAlphabet and nanoid functions of its non-secure module nanoid/non-secure. When these functions are given a negative size, the loop counter is decremented from a negative value and never reaches its termination condition, spinning...

CVE-2026-67213

CVE-2026-67213 (nanoid) affects Nano ID before 5.1.6. A bug in the customAlphabet and customRandom functions can enter an infinite loop when configured with a size of 0, causing the generation loop to spin and hang the calling thread. This creates a denial-of-service condition if an attacker can ...
