CVE-2026-30351
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 · uneditedA path traversal vulnerability in the UI/static component of leonvanzyl autocoder commit 79d02a allows attackers to read arbitrary files via sending crafted URL path containing traversal sequences.
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 · high confidenceA path traversal vulnerability exists in the UI/static component of leonvanzyl autocoder (commit 79d02a). Attackers can read arbitrary files on the server by including traversal sequences (such as ../) in the URL path when accessing static resources. This allows unauthorized access to sensitive files outside the intended static directory.

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.
-
Confirm leonvanzyl autocoder is installedLocate the autocoder application in your environment - check for the project directory, installed package, or running service. Identify the git repository or installation path.Affected if The product leonvanzyl autocoder is present in the environment
-
Identify the installed commit/versionCheck the git commit hash of the autocoder installation. Run 'git log' or check version metadata files in the project directory to determine if the installed version matches or predates commit 79d02a.Affected if The installed version matches commit 79d02a or is an earlier version
-
Verify static file serving is enabledInspect the application configuration files (such as config files, settings, or main entry point) to determine if static UI files are being served. Look for static file middleware, route handlers for /static/ or similar paths.Affected if Static file serving for the UI component is enabled and accessible via HTTP
-
Check web interface exposureVerify that the application's web interface is exposed externally or accessible to untrusted users. Check network configuration, firewall rules, or reverse proxy settings that expose the application ports.Affected if The application UI is accessible over the network to users who should not have file system access
-
Test for path traversal in static file requestsIf static serving is enabled and exposed, attempt a request with traversal sequences (such as ../../../../etc/passwd or similar) in the URL path to verify if arbitrary file access is possible. Compare the response to expected static file behavior.Affected if The application allows path traversal sequences and returns files outside the intended static directory
A user is affected if they have leonvanzyl autocoder at commit 79d02a or earlier with the UI static component enabled and accessible, and the application permits traversal sequences in static file requests to read arbitrary files.

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.
From vendor dataImplement strict input validation and path sanitization on all URL paths serving static files. Normalize paths and verify that resolved paths remain within the allowed static directory before file access.
