CVE-2026-58459Public exploit

Command injection via unescaped gnuplot title subtype

Published Jul 9, 2026 · Updated Jul 9, 2026

Command injection in GPSD Project gpsd 3.27.5 and earlier allows attackers to execute shell commands via crafted GPS subtype data. The gpsprof client copies a DEVICES JSON or NMEA PGRMT subtype into a generated gnuplot set title string while escaping quotes but not backticks. Execution occurs only when an operator profiles the malicious feed or log and renders the generated program with gnuplot, under the renderer user's privileges.
