Hi,

The following vulnerability was published for node-shell-quote.

CVE-2026-13311[0]:
| shell-quote prior to 1.8.5 finalizes parsed tokens in parse() using
| Array.prototype.concat as a reduce accumulator, which reallocates
| and copies the entire growing array on every iteration. As a result
| parse() runs in O(n^2) time relative to the number of input tokens.
| An attacker who can supply an attacker-controlled string to any code
| path that calls parse() (no shell metacharacters are required; plain
| space-separated words suffice) can block the single-threaded Node.js
| event loop for an extended period with a small input, resulting in a
| denial of service. There is no code execution or data disclosure;
| impact is to availability only. Fixed in 1.8.5.


If you fix the vulnerability please also make sure to include the
