CVE-2026-26318Public exploit

Local command execution via unsanitized locate output

Published Feb 19, 2026 · Updated Feb 19, 2026

OS command injection in systeminformation before 5.31.0 allows local users to execute commands through indexed filenames. The Linux-only versions() path sorts locate results, concatenates the last PostgreSQL path with -V, and passes the unsanitized string to exec(). Exploitation requires locate and an indexed PostgreSQL binary, a crafted filename included by updatedb, and an application call to versions(); commands run as the Node.js process.
