Vulnerability Details
CVE-2025-55319 is characterized by its AI command injection vulnerability. The primary vector involves network access, allowing attackers to execute malicious code remotely. The vulnerability type aligns with CWE-77, indicating command injection issues.
The vulnerability has a CVSS score of 8.8, which categorizes it as high severity due to its potential impact on confidentiality, integrity, and availability. The attack complexity is rated as low, and it requires no privileges but does necessitate user interaction.
Affected products are limited to versions of Microsoft Visual Studio Code prior to 1.104.0. Organizations should ensure they are running the latest version to mitigate this risk.
Technical Analysis
The root cause of CVE-2025-55319 stems from improper validation of input in the AI command execution context. Attackers may leverage this flaw through a network-based attack vector, which allows them to inject commands that the system will execute.
The attack complexity is considered low, with no privileges required for execution. However, user interaction is necessary for the exploitation to succeed. Once executed, the attacker may achieve a high level of confidentiality, integrity, and availability impact.
Risk & Impact Analysis
The real-world deployment risk tied to this vulnerability is significant. Organizations utilizing Visual Studio Code in environments that may be exposed to untrusted networks face an increased risk of unauthorized access and remote code execution.
The blast radius potential is considerable due to the widespread use of Visual Studio Code in software development. This vulnerability could allow an attacker to pivot to other parts of an organization’s infrastructure, leading to a broader compromise.
Given its CVSS score and the potential for exploitation, organizations should address this vulnerability in priority patch cycles. The urgency for remediation is high, as failure to patch could result in significant security incidents.
