No fix is confirmed yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for the fix.

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.
