NVD Description

Note: Versions mentioned in the description apply only to the upstream uptime-kuma-2.5 package and not the uptime-kuma-2.5 package as distributed by Minimos. See How to fix? for Minimos:latest relevant fixed versions and status.

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 passes an unvalidated, attacker-controlled size of 0 to these functions is exposed to a denial-of-service condition.
