Description

This security bulletin contains information about 1 vulnerability.


1) OS Command Injection (CVE-ID: CVE-2026-26318)

CWE-ID: CWE-78 - Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a local user to execute arbitrary commands.

The vulnerability exists due to command injection in the versions() function in lib/osinfo.js when processing locate output for PostgreSQL binary detection on Linux. A local user can create a file with a specially crafted pathname that is indexed by locate to execute arbitrary commands.

Exploitation requires a Linux system with locate installed, a PostgreSQL binary present in the locate database, and the attacker-controlled filename to be indexed by updatedb.
