{"schemaVersion":3,"id":"CVE-2021-24033","aliases":["GHSA-5q6m-3h65-w53x"],"status":"published","duplicateOf":null,"title":null,"description":"react-dev-utils prior to v11.0.4 exposes a function, getProcessForPort, where an input argument is concatenated into a command string to be executed. This function is typically used from react-scripts (in Create React App projects), where the usage is safe. Only when this function is manually invoked with user-provided values (ie: by custom code) is there the potential for command injection. If you're consuming it from react-scripts then this issue does not affect you.","dates":{"published":"2021-03-09T00:25:13.000Z","modified":"2024-08-03T19:21:17.286Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":6.8,"severity":"medium","version":"2.0","versionLabel":"v2.0","source":"NVD","vector":"AV:N/AC:M/Au:N/C:P/I:P/A:P","computed":false,"selection":"backend-summary"},"metrics":[{"version":"3.1","versionLabel":"v3.1","source":"OSV
