Prior to 2.1.14 and 3.0.1, getEscapeFunction in src/internal/win/cmd.js does not escape `(` and `)` when applications use the escape or escapeAll APIs on Windows with shell set to cmd.exe, or with shell set to true when CMD is the default. An attacker-controlled argument can break out of a parenthesized CMD construct and inject shell syntax depending on the original command, resulting in arbitrary command execution. This issue is fixed in versions 2.1.14 and 3.0.1.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","score":9.2},"cvss_v3":null,"cwes":["CWE-78","CWE-150"],"references":["https://github.com/ericcornelissen/shescape/commit/43d70b59d09bbe5c3fd02ef08b3a123e977ed9de","https://github.com/ericcornelissen/shescape/commit/b4b34c394e7f9da2775bb75381066b9a228c425f","https://github.com/ericcornelissen/shescape/pull/2649","https://github.com/ericcornelissen/shescape/pull/2651","https://github.com/ericcornelissen/shescape/releases/tag/v2.1.14"],"products":[],"source":"nvd","synced_at":"2026-10-24T16:53:35.584907681+00:00"},"epss":{"cve":"CVE-2026-73414","score":0.00889,"percentile":0.59079,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-w4hw-qcx7-56pr","url":"https://osv.dev/vulnerability/GHSA-w4hw-qcx7-56pr","summary":"Shescape: Shell injection via unescaped parentheses on Windows with CMD","modified":"2026-08-12T19:59:13.898763Z","packages":[{"ecosystem":"npm","name":"shescape","purl":"pkg:npm/shescape","ranges":["<2.1.14"],"fixed":["2.1.14"]},{"ecosystem":"npm","name":"shescape","purl":"pkg:npm/shescape","ranges":[">=3.0.0 <3.0.1"],"fixed":["3.0.1"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
