CVE-2026-30461Public exploitNetwork attack vector

Authenticated code execution via unquoted Git submodule command

Published Apr 15, 2026 · Updated Apr 15, 2026

Command injection in Daylight Studio FuelCMS 1.5.2 allows remote authenticated users to execute code through the module installer. The add_git_submodule method builds a git submodule add shell command from URI path segments without quoting or validation, then passes it to shell_exec. Exploitation requires development mode, Git-over-SSH setup, a valid .git directory, and an account permitted to use the installer; a malicious repository can place executable PHP in a web-accessible module directory.
