Prior to 5.31.7, networkInterfaces() on Linux is vulnerable to OS command injection through the Debian/Ubuntu interfaces(5) source directive because lib/network.js checkLinuxDCHPInterfaces() reads /etc/network/interfaces, extracts a source <path> token from file content, and interpolates it unquoted into cat ${file} 2> /dev/null | grep 'iface\\|source' executed by execSync(cmd, util.execOptsLinux), allowing a path containing shell metacharacters to execute commands in any process that calls networkInterfaces(), including via getStaticData() and getAllData(). This issue is fixed in version 5.31.7.","state":0,"publishedAt":"2026-07-17T19:42:41.417+00:00","modifiedAt":"2026-07-20T16:22:33.661+00:00","affected":[{"ecosystem":"Vendor product","name":"systeminformation","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"sebhildebrandt\",\n                    \"product\": \"systeminformation\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 5.31.7\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","score":8.7,"severity":"HIGH"}],"references":["https://github.com/sebhildebrandt/systeminformation/security/advisories/GHSA-5xpp-75jx-m839","https://github.com/sebhildebrandt/systeminformation/commit/bbfddde48672d0ee124fefdb3cb4442fd9dd4f03","https://github.com/sebhildebrandt/systeminformation/releases/tag/v5.31.7"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-50289","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-50289","identifiers":["CVE-2026-50289"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
