Atheos is a self-hosted browser-based cloud integrated development environment. Prior to version 6.0.4, improper use of `escapeshellcmd()` in `/components/codegit/traits/execute.php` allows argument injection, leading to arbitrary command execution. Atheos administrators and users of vulnerable versions are at risk of data breaches or server compromise. Version 6.0.4 introduces a `Common::safe_execute` function that sanitizes all arguments using `escapeshellarg()` prior to execution and migrated all components potentially vulnerable to similar exploits to use this new templated execution system.
The product constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command when it is sent to a downstream component.
