Technical details
A code injection vulnerability exists in libinput due to the improper loading of Lua plugins. The library uses the 'luaL_loadfile' function, which defaults to 'bt' (binary and text) mode, allowing the execution of unverified Lua bytecode. A local attacker with the ability to write to system or user configuration directories (e.g., /etc/libinput/plugins or XDG_CONFIG_HOME/libinput/plugins) can deploy a crafted bytecode file to bypass sandboxing and execute code with the privileges of the calling process, such as a Wayland compositor. This is particularly impactful on systems where libinput is compiled with '-Dautoload-plugins'. The issue is addressed in libinput versions 1.30.3 and 1.31.1 by switching to 'luaL_loadfilex' with text-only ('t') mode.
