GHSA-4vjg-vx72-qq4g: systeminformation (CVE-2026-116673)

Package	Ecosystem	Affected	Fixed in
systeminformation	npm	<5.33.14	5.33.14

Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

GHSA-4vjg-vx72-qq4g affects the npm package systeminformation before 5.33.14, where the Linux networkStats() function builds /sys/class/net paths from the caller-supplied interface value without confining the resolved path to that directory. An attacker who can control that value and create a symlink in the path could cause the function to return the first line of a file readable by the Node process. The advisory says remote exploitability through an application was not demonstrated. Upgrade to systeminformation 5.33.14 or later.
