Directory traversal vulnerability in chroot function in AtheOS 0.3.7 allows attackers to escape the jail via a .. (dot dot) in the pathname argument to chdir.

Improper Path Validation Enables Path Traversal in Multiple Components in Atheos

Atheos is a self-hosted browser-based cloud IDE. Prior to v600, the $path and $target parameters are not properly validated across multiple components, allowing an attacker to read, modify, or execute arbitrary files on the server. These vulnerabilities can be exploited through various attack vectors present in multiple PHP files. This vulnerability is fixed in v600.

Missing Path Validation Enables Path Traversal in Controller.php

Atheos is a self-hosted browser-based cloud IDE. Prior to v602, similar to GHSA-rgjm-6p59-537v/CVE-2025-22152, the `$target` parameter in `/controller.php` was not properly validated, which could allow an attacker to execute arbitrary files on the server via path traversal. v602 contains a fix for the issue.

Atheos Improper Input Validation Vulnerability Enables RCE in Common.php

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.
