CVE-2026-0774

Name of the Vulnerable Software and Affected Versions WatchYourLAN (affected versions not specified)

Description A network-adjacent attacker can execute arbitrary code on affected installations of WatchYourLAN without authentication. The issue stems from insufficient validation of user-supplied input for the arpstrs parameter before it is used in a system call, leading to argument injection. Successful exploitation allows an attacker to execute code with the privileges of the service account.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
