CVE-2026-6835
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 · uneditedThe a+HCM developed by aEnrich has an Arbitrary File Upload vulnerability, allowing unauthenticated remote attackers to upload arbitrary files to any path, including HTML documents, which may result in a XSS-like effect.
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 confidenceThe a+HCM application by aEnrich contains an unauthenticated arbitrary file upload vulnerability that allows remote attackers to upload files to any path on the server. Since HTML files can be uploaded, this enables stored XSS attacks when users access the uploaded malicious files.

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.
-
Identify if a+HCM application is presentCheck running web applications or examine web server logs for requests to aEnrich a+HCM endpoints. Look for application fingerprints such as URL paths containing '/aHcm/', '/api/upload', or page titles referencing 'aEnrich' or 'a+HCM'.Affected if The a+HCM application by aEnrich is installed and exposed on the network.
-
Determine if file upload endpoints allow unauthenticated accessAttempt to access common file upload paths such as '/upload', '/api/upload', '/file/upload', or '/hcm/upload' without providing any authentication credentials. Use curl or a browser to send a GET or POST request to these endpoints.Affected if The upload endpoint returns a valid response (accepting files) without requiring login or session authentication.
-
Check if path traversal is possible in upload parametersInspect the upload form or API parameters for a path field. Attempt to include path traversal sequences like '../' or absolute paths in the upload request to see if files can be written outside the intended directory.Affected if Files can be saved to arbitrary directories by manipulating the upload path parameter.
-
Verify if HTML file uploads are permittedUpload a test file with an .html extension containing a benign script tag. Send a POST request to the upload endpoint with Content-Type multipart/form-data and the file in the appropriate field.Affected if The server accepts and stores .html files without rejecting them based on file type validation.
-
Confirm uploaded files are web-accessibleAfter uploading a test file, try to access it via a direct URL through the web browser or curl. Check if the uploaded file is served from the web root or a publicly reachable path.Affected if Uploaded files are stored in a web-accessible location and can be accessed via HTTP/HTTPS.
If the a+HCM application is exposed and its file upload endpoint accepts unauthenticated requests that allow saving files to arbitrary paths including .html files in web-accessible locations, the environment is affected by CVE-2026-6835.

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 proper authentication for file upload endpoints, validate file types using magic bytes not just extensions, prevent path traversal in upload paths, and store uploaded files outside the web root or in a non-executable location.
