Not failing securely ('failing open') in Visual Studio Code allows an unauthorized attacker to bypass a security feature over a network.
AnalysisAI
Security feature bypass in Visual Studio Code before 1.136.2 allows a remote, unauthenticated attacker to circumvent a protection mechanism via a failing-open (CWE-636) code path, resulting in high confidentiality impact and limited integrity impact across a changed scope. The vulnerability is reachable over the network with low complexity but requires user interaction, suggesting an attacker must induce the victim to open a crafted workspace, file, or URI. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | User interaction is required: the victim must open a crafted workspace, folder, URI, or file in VS Code (PR:N but UI:R). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 8.2 vector (AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:L/A:N) is internally consistent with the failing-open description: a remote, unauthenticated attacker can trigger the bypass with low effort, but must engineer user interaction - the primary real-world friction. … 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 contains the vendor-released fix. … Detailed patch versions, workarounds, and compensating controls in full report. |
