NVD Description

luci-app-https-dns-proxy through 2025.12.29-5 — an optional LuCI web UI add-on for the https-dns-proxy package, distributed through the OpenWrt community packages feed and not installed by default — contains a command injection vulnerability in the setInitAction function. An authenticated user holding…
