CVE-2026-19045 in LudusMCP
Summary
by MITRE • 08/06/2026
A weakness has been identified in NocteDefensor LudusMCP up to 1.0.24. The affected element is the function SecretDialog.showSecretDialog of the file src/utils/secretDialog.ts of the component get_credential_from_user. This manipulation of the argument Description causes command injection. It is possible to launch the attack on the local host. The project was informed of the problem early through an issue report but has not responded yet.

The vulnerability identified in NocteDefensor LudusMCP version 1.0.24 represents a critical command injection flaw within the get_credential_from_user component's SecretDialog.showSecretDialog function. This weakness resides in the src/utils/secretDialog.ts file where the Description argument is improperly handled, creating an avenue for malicious code execution on the local host system. The vulnerability stems from inadequate input validation and sanitization mechanisms that fail to properly process user-supplied data before incorporating it into system commands.
The technical implementation of this flaw demonstrates a classic command injection vulnerability where attacker-controlled input flows directly into shell execution contexts without proper escaping or sanitization. When the Description parameter is manipulated, it bypasses normal input processing boundaries and gets executed as part of the underlying operating system commands. This type of vulnerability falls under CWE-78 which specifically addresses improper neutralization of special elements used in OS commands, making it particularly dangerous in desktop applications that execute system-level operations.
The operational impact of this vulnerability extends beyond simple code execution to encompass full system compromise potential on the local host environment. An attacker could leverage this weakness to execute arbitrary commands with the privileges of the application process, potentially leading to privilege escalation scenarios, data exfiltration, or system persistence mechanisms. The fact that this affects a credential retrieval component adds significant risk as attackers could manipulate the dialog behavior to capture or alter authentication flows, making it particularly attractive for adversary operations targeting sensitive credential management systems.
From an attack perspective, this vulnerability aligns with ATT&CK technique T1059.001 which covers command and scripting interpreter execution. The local host attack vector eliminates network-based defense mechanisms and allows for more direct exploitation approaches. The issue has been reported through proper channels via issue reporting but remains unaddressed by the project maintainers, creating a window of opportunity for potential exploitation in environments where this software is deployed.
Mitigation strategies should prioritize immediate input sanitization and validation of all user-supplied parameters passed to system execution contexts. Implementing proper parameter escaping, using secure API calls instead of shell command construction, and adopting principle of least privilege for application processes are essential defensive measures. Additionally, regular security audits and vulnerability assessments should be conducted to identify similar patterns in other components, as this vulnerability type often appears in applications that handle user input with insufficient sanitization mechanisms across various system interaction points within desktop applications.
