CVE-2025-22152
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedAtheos 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.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceAtheos cloud IDE versions prior to v600 lack proper validation on $path and $target parameters across multiple PHP components, enabling path traversal attacks that allow unauthenticated attackers to read, modify, or execute arbitrary files on the server filesystem.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify Atheos installation versionLocate the version file or index.php in the web root and check the version string against v600Affected if The installed version is below v600 (e.g., v5.x, v4.x, etc.)
-
Locate PHP components handling file operationsSearch the Atheos installation directory for PHP files that reference $path or $target parameters in function signatures, particularly in components handling file uploads, downloads, or file managementAffected if Multiple PHP files with unvalidated $path or $target parameters exist in the codebase
-
Verify input validation on file operation endpointsInspect the identified PHP files for path validation logic (e.g., realpath(), basename(), whitelist checks) before file operationsAffected if No validation or weak validation (missing realpath() checks) is present on $path/$target parameters
-
Check exposure of file operation endpointsDetermine if the affected PHP endpoints are accessible without authentication by examining authentication/authorization logic in the codebaseAffected if File operation endpoints accept requests without requiring authentication
-
Assess server filesystem accessReview if the web server user has permissions to access sensitive directories outside the intended workspace rootAffected if The web server process has read/write access to system files or directories outside the intended Atheos workspace folder
You are affected if your Atheos installation is version prior to v600 and the PHP components with unvalidated $path/$target parameters are accessible to unauthenticated users.
Generated from the published advisory. Verify against your own configuration.
Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scopedUpgrade to v600 immediately, or if immediate upgrade is not feasible, implement strict input validation and whitelist-based path sanitization on all file operation endpoints in the affected PHP files.
v600
- Backup your current Atheos installation and database
- Download Atheos v600 from the official GitHub repository
- Replace the existing Atheos files with the v600 files
- Verify that $path and $target parameter validation is now properly implemented across PHP components
- Test that file operations within the IDE work as expected
