Description

A flaw was found in the `shell-quote` component. An attacker who can supply a specially crafted string to the `parse()` function can exploit an inefficiency in how the component processes input. This can cause the single-threaded Node.js event loop to be blocked for an extended period, leading to a denial of service (DoS) for the affected system. The vulnerability impacts the availability of the system, with no risk of code execution or data disclosure.
