CVE-2026-2684
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 vulnerability was determined in Tsinghua Unigroup Electronic Archives System up to 3.2.210802(62532). The impacted element is an unknown function of the file /Archive/ErecordManage/uploadFile.html. Executing a manipulation of the argument File can lead to unrestricted upload. The attack may be launched remotely. The exploit has been publicly disclosed and may be utilized. The vendor was contacted early about this disclosure but did not respond in any way.
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 confidenceTsinghua Unigroup Electronic Archives System versions up to 3.2.210802(62532) contain an unrestricted file upload vulnerability in /Archive/ErecordManage/uploadFile.html. The 'File' parameter accepts arbitrary file uploads without proper validation, potentially allowing remote code execution if the uploaded file is placed in a web-accessible location.

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 installed version of Electronic Archives SystemLocate the application installation directory or check system configuration files for version information. Compare the found version number to the affected range: versions <= 3.2.210802(62532)Affected if The installed version is 3.2.210802(62532) or lower
-
Verify vulnerable endpoint existsCheck if the file /Archive/ErecordManage/uploadFile.html exists in the webroot of the applicationAffected if The uploadFile.html file exists in the expected path
-
Confirm upload functionality is enabledAttempt to access the upload endpoint via HTTP GET request to /Archive/ErecordManage/uploadFile.html and verify the page loads or respondsAffected if The endpoint is accessible and responds to requests
-
Check web server configuration for upload handlingReview web server (e.g., Apache, Nginx, IIS) configuration to determine if uploaded files are placed in web-accessible directoriesAffected if Uploaded files can be served from web-accessible paths, enabling RCE potential
The environment is affected if the Electronic Archives System version is 3.2.210802(62532) or lower AND the /Archive/ErecordManage/uploadFile.html endpoint exists and is accessible, allowing unrestricted file uploads to web-accessible locations.

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 allowlist-based file type validation, enforce file size limits, rename uploaded files, store uploads outside webroot, and disable script execution in the upload directory. If possible, disable the affected endpoint until proper controls are implemented.
