CVE-2026-44724Public exploit

Local command execution via unsanitized connection names

Published May 27, 2026 · Updated May 27, 2026

Command injection in Sebastian Hildebrandt systeminformation 4.17.0 through 5.31.5 on Linux allows local users to execute commands via profile names. networkInterfaces() parses an active NetworkManager connection name from nmcli output and interpolates it unsanitized into three execSync() shell strings. A local user must be able to create or rename an active connection profile; injected commands run with the Node.js process privileges.
