CVE-2026-13311 shell-quote parse() is quadratic in token count, enabling denial of service

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 On^2 time relative to the number of input tokens. An attacker who can supply an...

CVE-2026-13311

The CVE affects the shell-quote library prior to version 1.8.5. The parse() function accumulates tokens by using Array.prototype.concat as a reduce accumulator, causing O(n^2) time relative to token count and enabling a potential denial of service by blocking the Node.js event loop with small, at...
