Executive Summary

CVE-2026-19046 is a path traversal vulnerability in NocteDefensor LudusMCP up to version 1.0.24. It affects the ludus_environment_guides_search tool where a user-controlled guide_name parameter is directly joined to a base directory path without validation. This allows attackers to traverse outside the intended directory and read arbitrary files on the system, subject to the running process's filesystem permissions.

Detection Guidance

To detect this vulnerability, inspect the LudusMCP installation for the vulnerable files src/tools/ludusEnvironmentGuidesSearch.ts and src/tools/ludusDocsSearch.ts. Check if the code uses path.join(guidesDir, guideName) or similar without validating the final path. Look for user-controlled parameters like guide_name or search_directory being directly concatenated to base directories.

Impact Analysis

An attacker with local access could exploit this to read sensitive files outside the documentation directory, such as configuration files, credentials, or other system files. The impact depends on the permissions of the LudusMCP process. For example, if the process runs with elevated privileges, it could expose critical system files.

Compliance Impact

This vulnerability could lead to unauthorized access to sensitive data, violating compliance requirements like GDPR (data protection) or HIPAA (health information privacy). If exploited, it may result in data breaches, unauthorized disclosure of personal or health information, and failure to meet regulatory safeguards for data confidentiality and integrity.

Mitigation Strategies

Immediately update LudusMCP to the latest version if a patch is available. If not, restrict access to the vulnerable tools by modifying permissions or disabling the documentation search features. Implement input validation to reject traversal sequences like .. in guide_name and search_directory parameters. Ensure file paths are resolved and checked to remain within intended directories before reading.
