9.6 CRITICAL

Network-delivered malicious content requires victim interaction (UI:R) but no auth (PR:N); a security-feature bypass crossing the editor trust boundary supports S:C with high C/I/A, matching the vendor rating.

DescriptionCVE.org

Incomplete comparison with missing factors in Visual Studio Code allows an unauthorized attacker to bypass a security feature over a network.

AnalysisAI

Security-feature bypass in Microsoft Visual Studio Code before 1.136.2 lets a remote, unauthenticated attacker defeat a protection mechanism when a user is lured into interacting with malicious content (UI:R). Rooted in an incomplete comparison that omits required factors (CWE-693), the flaw carries a scope-changed CVSS 9.6 with full confidentiality, integrity, and availability impact, consistent with a trust/security-control bypass that can extend beyond the editor's initial boundary. …

Vulnerability AssessmentAI

Exploitation Requires victim user interaction (CVSS UI:R): a developer must open or interact with attacker-controlled content in an affected VS Code build (1.0.0 through <1.136.2) - for example a malicious workspace/repository, crafted file, or untrusted URI handled by the editor. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The signals are mostly aligned toward high priority: CVSS 9.6 with AV:N/AC:L/PR:N reflects an unauthenticated, low-complexity network vector, and S:C with C:H/I:H/A:H implies the bypass crosses a security boundary into broader impact - plausible for an editor that can execute tasks or extensions. … 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, which is the first fixed release per ENISA EUVD data; VS Code's built-in auto-update generally delivers this, but managed/offline deployments should push the update explicitly and verify the running version. … Detailed patch versions, workarounds, and compensating controls in full report.

Recommended ActionAI

Within 24 hours, identify all Visual Studio Code installations across development environments and document current version numbers using asset management or endpoint-detection tools. …
