CVE-2026-45496
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedImproper limitation of a pathname to a restricted directory ('path traversal') in Visual Studio Code allows an unauthorized attacker to bypass a security feature locally.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceA path traversal vulnerability in Visual Studio Code allows a local attacker to bypass a security feature by manipulating file paths to access resources outside restricted directories. The vulnerability stems from improper validation of file path inputs.
Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Check installed Visual Studio Code versionOpen VS Code and go to Help > About, or run `code --version` from command lineAffected if Version number is lower than 1.128.1 (e.g., 1.128.0, 1.127.x, earlier)
-
Verify VS Code editionConfirm you are using Microsoft Visual Studio Code (not VS Code Insiders or open-source builds) - check the application name in the title bar or About dialogAffected if Running Microsoft Visual Studio Code
-
Review file access patternsInspect any workspace settings, tasks, or extensions that involve file path operations, particularly those accessing files outside the workspace rootAffected if Using file path features with paths that could potentially escape restricted directories
If Visual Studio Code version is below 1.128.1 and you work with file paths across directories, your environment is likely affected by this path traversal vulnerability.
Generated from the published advisory. Verify against your own configuration.
Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped1.128.1
Apply the official Visual Studio Code security update or patch to address the path traversal issue. Ensure local workspace settings and extensions are reviewed for potential bypass vectors.
Visual Studio Code 1.128.1
- Open Visual Studio Code
- Navigate to Help > Check for Updates (or press Ctrl+Shift+P and run 'Check for Updates')
- Allow VS Code to download and install version 1.128.1 or later
- Restart Visual Studio Code to complete the update
