CVE-2026-102232 Overview
CVE-2026-102232 is an incorrect authorization vulnerability [CWE-863] in Microsoft Visual Studio Code. An unauthorized local attacker can bypass a security feature when a user is tricked into performing a specific action. The flaw affects the confidentiality, integrity, and availability of the host, with all three rated high in the CVSS vector. Exploitation requires local access, user interaction, and high attack complexity, which lowers the practical attack surface. Microsoft published advisory details through the Microsoft Security Response Center.
Critical Impact
A successful bypass allows a local attacker to circumvent a security control in Visual Studio Code, with high impact to confidentiality, integrity, and availability on the affected workstation.
Affected Products
- Microsoft Visual Studio Code
- Specific affected versions are listed in the Microsoft CVE-2026-102232 Advisory

Technical Details for CVE-2026-102232
Vulnerability Analysis
The vulnerability is categorized as incorrect authorization [CWE-863]. Visual Studio Code performs an authorization decision that does not correctly validate the requesting context. A local attacker can leverage this logic gap to bypass a security feature intended to restrict a privileged or protected action. The attack requires user interaction, meaning the victim must open a file, workspace, or extension-triggered action controlled by the attacker. Successful exploitation yields high impact across confidentiality, integrity, and availability within the user's security context.
Root Cause
The root cause is an authorization check in Visual Studio Code that does not fully enforce the intended security boundary. When the check is reached under specific conditions, the editor permits an action it should block. Microsoft classifies this as a security feature bypass rather than remote code execution, though the downstream impact on the local system is still high.
Attack Vector
The attack vector is local. An attacker needs to deliver a crafted project, workspace file, or extension payload to the target developer. The user must then perform an action, such as opening the workspace or trusting a prompt, that triggers the flawed authorization path. High attack complexity reflects the specific preconditions required for reliable exploitation. See the Microsoft CVE-2026-102232 Advisory for vendor-specific exploitation prerequisites.

Stop Identity AttacksDetection Methods for CVE-2026-102232
Indicators of Compromise
- Unexpected Visual Studio Code workspace trust prompts followed by execution of local scripts or tasks
- Newly installed or sideloaded .vsix extensions from untrusted sources
- Visual Studio Code child processes spawning shells, package managers, or powershell.exe outside normal developer workflows
- Modifications to .vscode/tasks.json, .vscode/launch.json, or settings.json originating from downloaded repositories
Detection Strategies
- Monitor process lineage where Code.exe or code is the parent of interpreters, compilers, or scripting hosts outside expected build activity
- Alert on Visual Studio Code reading or writing files outside the active workspace shortly after opening a new project
- Track installation of extensions outside the Visual Studio Marketplace or outside corporate allowlists
Monitoring Recommendations
- Enable endpoint telemetry for developer workstations and retain Visual Studio Code process events for post-incident analysis
- Review workspace trust decisions and extension installation audit logs on a recurring cadence
- Correlate repository clone events with subsequent Visual Studio Code task execution to spot social-engineering patterns
How to Mitigate CVE-2026-102232
Immediate Actions Required
- Update Visual Studio Code to the fixed build identified in the Microsoft CVE-2026-102232 Advisory
- Audit installed extensions and remove any from untrusted publishers
- Instruct developers to avoid opening untrusted repositories without using Restricted Mode
Patch Information
Microsoft has issued a security update for Visual Studio Code addressing the incorrect authorization flaw. Refer to the Microsoft CVE-2026-102232 Advisory for the exact fixed versions and distribution channels. Visual Studio Code auto-updates by default; verify that managed deployments are not pinned to vulnerable builds.
Workarounds
- Enforce Workspace Trust and keep untrusted folders in Restricted Mode until patched
- Restrict extension installation to an organizational allowlist via group policy or managed configuration
- Avoid cloning or opening repositories from untrusted sources on unpatched systems
# Verify installed Visual Studio Code version
code --version
# Enforce Workspace Trust via settings.json
# "security.workspace.trust.enabled": true,
# "security.workspace.trust.startupPrompt": "always",
# "security.workspace.trust.untrustedFiles": "prompt",
# "extensions.autoUpdate": true
