For developers and IT administrators, the practical priority is updating Visual Studio Code—not simply avoiding unfamiliar source code. Microsoft’s advisory identifies imported profiles, content, and links as potential delivery routes.
Vulnerability details
Microsoft’s Security Response Center provides the following assessment:
| Field | Official value |
|---|---|
| CVE | CVE-2026-102238 |
| Exact title | Visual Studio Code Remote Code Execution Vulnerability |
| Affected product | Visual Studio Code |
| Severity | Important |
| CVSS base score | 9.6 |
| CVSS temporal score | 8.3 |
| Weakness | CWE-22 |
| Vendor fixed build | 1.141.1 |
| Exploitation assessment | Exploitation Less Likely |
CVSS vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H/E:U/RL:O/RC:C
- Publicly disclosed: No
- Exploited: No
- Customer action required: Yes
These status values describe Microsoft’s advisory assessment; they are not a reason to postpone remediation. Likewise, Microsoft’s Important severity designation and the 9.6 CVSS base score are distinct assessment values, rather than interchangeable labels.
How the attack works
Microsoft describes the flaw as improper limitation of a pathname to a restricted directory—path traversal—in Visual Studio Code, allowing an unauthorized attacker to execute code over a network.
The advisory outlines a user-mediated attack: an attacker could convince someone to import a specially crafted Visual Studio Code profile or open specially crafted content or links. Successful exploitation could bypass path-containment checks, permit access outside intended locations, and potentially result in code execution in the context of the user.
The crucial boundary is therefore where the application is supposed to keep file access confined. In practical terms, path-containment checks act like a fence around permitted locations. This vulnerability offers a way past that fence; Microsoft identifies code execution as a possible consequence.
The supplied CVSS vector adds useful context to that attack description:
- Network access and low attack complexity: The scoring models a network-based attack without high complexity.
- No attacker privileges required, but user interaction required: This is not described as an attack that succeeds merely because the editor is installed. Persuading the user to interact with crafted material is part of the scenario.
- Changed scope and high confidentiality, integrity, and availability impacts: The scoring reflects potentially serious consequences across all three impact categories.
This interpretation follows the supplied vector and advisory, rather than suggesting additional attack techniques.
What to update and verify
Microsoft’s remediation is explicit:
For Visual Studio Code, update to fixed build 1.141.1 or later.
The affected-product record maps Visual Studio Code to fixed build 1.141.1. That gives administrators a concrete deployment target and a straightforward verification criterion.
For an operational response:
- Identify Visual Studio Code installations within the environment you manage.
- Deploy the update through your established software-management process, using Microsoft’s fixed-build target.
- Verify the installed build after deployment. A queued or approved update is not the same as a completed installation.
- Remind users about the advisory’s specific interaction routes: importing profiles and opening crafted content or links.
That final point matters for developer security communications. A warning limited to suspicious code repositories would not cover every route Microsoft describes. Profiles and links belong in the message too.
As a precaution while updates are being deployed, treat unexpected profiles, content, and links cautiously. This is risk-reduction guidance derived from the documented attack scenario, not a substitute for the fixed build.
Bottom line
CVE-2026-102238 requires a Visual Studio Code update to 1.141.1 or later. Microsoft assesses exploitation as less likely, but the documented combination of path-containment bypass and potential execution as the user warrants prompt attention.
For IT teams, success means confirming the installed build meets the remediation target. For developers, the key lesson is equally concrete: potentially dangerous input can arrive as an editor profile or a link, not just as code you deliberately choose to run.
