Detailed vulnerability description
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.
