If (attacker-controlled) user input is given, it is possible for an attacker to execute arbitrary commands. This is due to use of the child_process exec function without input sanitization. Running this PoC will cause the command touch success to be executed, leading to the creation of a file called success.","published":"2021-03-21T16:15:12.720Z","modified":"2026-07-08T06:49:34.573648300Z","cvss":{"score":8.8,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[{"ecosystem":"npm","name":"killport","fixedVersion":"1.0.2"}],"fix":{"url":"https://github.com/ssnau/killport/commit/bec8e371f170a12e11cd222ffc7a6e1ae9942638","label":"ssnau/killport@bec8e37"},"references":[{"type":"WEB","url":"https://github.com/ssnau/killport/blob/5268f23ea8f152e47182b263d8f7ef20c12a9f28/index.js%23L9"},{"type":"FIX","url":"https://github.com/ssnau/killport/commit/bec8e371f170a12e11cd222ffc7a6e1ae9942638"},{"type":"FIX","url":"https://snyk.io/vuln/SNYK-JS-KILLPORT-1078535"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-07-08T06:49:34.573648300Z"}}
