Vulnerability Details
The official description of CVE-2025-24042 states: 'Visual Studio Code JS Debug Extension Elevation of Privilege Vulnerability'. This vulnerability falls under the CWE classification of 'CWE-284: Improper Access Control'.
The CVSS v3.1 score of 7.3 indicates a high severity level. Key metrics define this vulnerability as having a local attack vector with low attack complexity, and it requires low privileges and user interaction. The impacts on confidentiality, integrity, and availability are all categorized as high.
Microsoft Visual Studio Code versions prior to 1.97.1 are affected. Organizations should ensure they update to the latest version to mitigate this risk.
Technical Analysis
The root cause of this vulnerability stems from improper access controls within the JS Debug Extension. Attackers may exploit this flaw to gain elevated privileges, which could allow them to execute arbitrary code or otherwise manipulate the development environment.
The attack vector is local, meaning that an attacker must have physical or remote access to the system where Visual Studio Code is installed. The attack complexity is low, indicating that a simple method could be used to exploit the vulnerability, especially if the user is tricked into executing malicious code.
Low privileges are required for exploitation, and user interaction is necessary, as the attacker would likely need the user to perform a specific action that triggers the exploit.
The confidentiality, integrity, and availability impacts are all rated high, emphasizing the severity of the potential consequences if exploited.
Risk & Impact Analysis
Real-world deployment risk stems from the potential for attackers to leverage this vulnerability to escalate privileges, leading to unauthorized access to sensitive development environments and data. Given the widespread use of Microsoft Visual Studio Code, the potential blast radius is significant, affecting numerous organizations and developers.
Organizations should assess their risk posture and prioritize remediation efforts based on their reliance on Microsoft Visual Studio Code. The urgency of addressing this vulnerability is underscored by its CVSS score, which indicates a high severity and the need for immediate action.
