Openwrt · Luci-App-Tailscale-Community · CVE-2026-57999
**Name of the Vulnerable Software and Affected Versions**
luci-app-tailscale-community (affected versions not specified)
**Description**
An issue in the `tailscale.do login` RPC method allows authenticated users to execute arbitrary commands with root privileges. This occurs because the `loginserver` and `loginserver authkey` parameters are improperly quoted within a double-quoted shell command, enabling shell substitutions such as `$()` to be evaluated by the outer shell before argument processing.
**Recommendations**
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
