EUVD-2026-10791

Comprehensive Technical Analysis of EUVD-2026-10791

1. Vulnerability Assessment and Severity Evaluation

The vulnerability identified in the simple-git library, an interface for running git commands in Node.js applications, is critical. The issue allows an attacker to bypass two prior CVE fixes (CVE-2022-25860 and CVE-2022-25912) and achieve full remote code execution (RCE) on the host machine. The severity of this vulnerability is underscored by its CVSS (Common Vulnerability Scoring System) base score of 9.8, which is classified as critical. The CVSS vector CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H indicates the following:

• Attack Vector (AV): Network (N) - The vulnerability is exploitable over the network.
• Attack Complexity (AC): Low (L) - The attack requires minimal complexity.
• Privileges Required (PR): None (N) - No privileges are required to exploit the vulnerability.
• User Interaction (UI): None (N) - No user interaction is required.
• Scope (S): Unchanged (U) - The vulnerability does not change the security scope.
• Confidentiality (C): High (H) - There is a high impact on confidentiality.
• Integrity (I): High (H) - There is a high impact on integrity.
• Availability (A): High (H) - There is a high impact on availability.

2. Potential Attack Vectors and Exploitation Methods

Given the nature of the vulnerability, potential attack vectors include:

• Network-Based Attacks: Since the attack vector is network-based, an attacker could exploit this vulnerability remotely without needing physical access to the system.
• Malicious Inputs: An attacker could craft malicious inputs that bypass the existing security measures and execute arbitrary code on the host machine.
• Supply Chain Attacks: If an attacker can inject malicious code into the simple-git library or any dependent libraries, they could exploit this vulnerability to compromise systems that use the library.

3. Affected Systems and Software Versions

The vulnerability affects simple-git versions 3.15.0 through 3.32.2. The updated fix is available in version 3.23.0. Organizations using any of the affected versions are at risk and should prioritize updating to the patched version.

4. Recommended Mitigation Strategies

To mitigate the risk associated with this vulnerability, the following strategies are recommended:

• Immediate Patching: Upgrade to simple-git version 3.23.0 or later, which contains the updated fix for the vulnerability.
• Network Segmentation: Implement network segmentation to limit the attack surface and reduce the risk of lateral movement by attackers.
• Input Validation: Ensure robust input validation and sanitization to prevent malicious inputs from being processed.
• Monitoring and Logging: Enhance monitoring and logging to detect any suspicious activities that may indicate an attempt to exploit this vulnerability.
• Regular Security Audits: Conduct regular security audits and vulnerability assessments to identify and address potential security issues proactively.

5. Impact on European Cybersecurity Landscape

The vulnerability in simple-git poses a significant risk to the European cybersecurity landscape, particularly for organizations that rely on Node.js applications. The potential for full remote code execution means that attackers could gain complete control over affected systems, leading to data breaches, service disruptions, and other severe consequences. This underscores the importance of timely patching and robust security practices to protect against such threats.

6. Technical Details for Security Professionals
