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."}], "lastModified": "2026-06-26T19:03:34.507", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:shell-quote_project:shell-quote:*:*:*:*:*:node.js:*:*", "vulnerable": true, "matchCriteriaId": "857C16CB-E752-4E3D-A096-79E73102BEB8", "versionEndExcluding": "1.9.0"}], "operator": "OR"}]}], "sourceIdentifier": "7ffcee3d-2c14-4c3e-b844-86c6a321a158"}
