Vulnerability in 1panel-Dev Maxkb
CVE-2026-79919
MaxKB is an open-source AI assistant for enterprise. Prior to version 2.10.6-lts, function-library code running under the LD_PRELOAD sandbox can invoke ctypes.CDLL from an importlib.abc.MetaPathFinder callback so the dlopen call-stack heuristic sees a Python import frame, then use unhooked dlsym with RTLD_NEXT to resolve glibc's real syscall and bypass the sandbox syscall blacklist. An authenticated workspace member can consequently read or write files, execute processes, or access networks as the sandbox user. This issue is fixed in version 2.10.6-lts.
