DescriptionCVE.org

Server-side request forgery (ssrf) in Visual Studio Code allows an unauthorized attacker to bypass a security feature over a network.

AnalysisAI

Server-side request forgery in Visual Studio Code prior to 1.136.2 allows a remote unauthenticated attacker to bypass security features and force VS Code to issue HTTP requests to internal or otherwise restricted network resources on the victim's behalf. Exploitation requires user interaction - a developer must open or trigger attacker-controlled content within VS Code - after which the editor acts as a request proxy, crossing trust boundaries (S:C) to reach endpoints inaccessible from the attacker's network position. …

Vulnerability AssessmentAI

Exploitation User interaction is required: the victim developer must open or trigger attacker-controlled content within VS Code (confirmed by UI:R in the CVSS vector). … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 8.2 (AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:L/A:N) accurately reflects the key risk dimensions: low attack complexity, no attacker authentication requirement, network delivery, and high confidentiality impact via internal resource exposure. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario Full exploit scenario with step-by-step reproduction available after sign-in.
Remediation Upgrade Visual Studio Code to version 1.136.2 or later. … Detailed patch versions, workarounds, and compensating controls in full report.

Recommended ActionAI

Within 24 hours, notify all development teams of the vulnerability and begin inventorying VS Code deployments across the organization. …
