SCA: security update for 9router (GHSA-g6g7-pvmx-m74p)
critical Tenable Cloud Security Plugin ID 444478
Description
There are packages installed that are affected by a vulnerability referenced in the following CVE:- 9Router before 0.4.44 contains an OS command injection vulnerability in the unauthenticated POST
/api/tunnel/tailscale-install endpoint (this route is not covered by the dashboard middleware matcher, so
no authorization check is applied). The sudoPassword field from the request body is written to the stdin
of a 'sudo -S sh' child process. When sudo does not prompt for a password (the process runs as root,
NOPASSWD is configured, or a recent sudo timestamp cache exists), the sudoPassword value is interpreted by
sh as a shell command, allowing a remote unauthenticated attacker to execute arbitrary OS commands.
Exploitation evidence was first observed by the Shadowserver Foundation on 2026-07-04 (UTC).
(CVE-2026-59800)
Solution
Update the 9router library and its related packages to version 0.4.44 or later.See Also
