CVE-2026-19366 Details
Description
A flaw has been found in NocteDefensor LudusMCP up to 1.0.24. Affected is an unknown function of the file src/tools/insertCredsRangeConfig.ts of the component insert_creds_range_config. Executing a manipulation of the argument configPath/outputPath can lead to path traversal. The attack is restricted to local execution. The project was informed of the problem early through an issue report but has not responded yet.
A path traversal vulnerability has been identified in NocteDefensor LudusMCP versions through 1.0.24. The issue arises in the insert_creds_range_config component, specifically within the src/tools/insertCredsRangeConfig.ts file. The vulnerability allows for arbitrary file read and write operations by manipulating the configPath and outputPath arguments. This exploitation can be executed locally, bypassing intended path restrictions.
It is recommended to update the insert_creds_range_config tool to reject absolute paths for configPath and outputPath. Implement normalization and resolution of paths, ensuring they remain within the allowed directory. Additionally, remove traversal segments such as '..' and apply stricter validation using the logic from other range configuration tools.
