Path Traversal in Atomic Agents Stack Dashboard

Publication date: 2026-09-15

Last updated on: 2026-09-15

Assigner: VulnCheck

Description
atomic-agents-stack before 1.1.0 contains a path traversal vulnerability in the dashboard HTTP server that allows remote attackers to read arbitrary files by supplying directory traversal sequences in request paths. Attackers can bypass path containment checks by including '../' segments in requests to the DashboardHandler.do_GET endpoint to access files outside the intended agents_root directory.

Executive Summary

This vulnerability is a path traversal issue in the atomic-agents-stack software before version 1.1.0. It allows remote attackers to read arbitrary files on the system by including directory traversal sequences like '../' in HTTP request paths to the DashboardHandler.do_GET endpoint. This bypasses intended path containment checks and grants access to files outside the designated agents_root directory.

Detection Guidance

To detect this vulnerability, monitor HTTP requests to the DashboardHandler.do_GET endpoint for path traversal patterns like '../'. Use tools like curl to test if arbitrary files can be accessed by sending requests with encoded '../' sequences in the path.

Impact Analysis

This vulnerability could allow unauthorized access to sensitive files on your system, including configuration files, logs, or other confidential data. Attackers might exploit it to steal information, escalate privileges, or perform further attacks if they gain access to critical files.

Compliance Impact

This vulnerability could lead to non-compliance with GDPR, HIPAA, or other regulations by exposing sensitive personal or health data. Unauthorized file access may result in data breaches, violating privacy requirements and potentially leading to legal penalties or reputational damage.

Mitigation Strategies

Immediately upgrade atomic-agents-stack to version 1.1.0 or later. If upgrading is not possible, restrict access to the dashboard HTTP server and implement strict input validation to block path traversal sequences in request paths.
