NVD Description

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

nanoid (Nano ID) before 3.3.16 and 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 indefinitely and hanging the calling thread. An application that passes an unvalidated, attacker-controlled negative size to these functions is exposed to a denial-of-service condition.
