CVE-2026-45419
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 · uneditedDataEase is an open source data visualization and analysis tool. Prior to 2.10.23, DataEase template saves call TemplateManageService#save, StaticResourceServer#saveFilesToServe, and the /de2api/templateManage/save endpoint with attacker-controlled staticResource names and Base64 content, allowing path traversal and arbitrary file writes because only / was used when extracting the file name. This issue is fixed in version 2.10.23.
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 confidenceDataEase versions prior to 2.10.23 contain a path traversal vulnerability in the template save functionality (TemplateManageService#save, StaticResourceServer#saveFilesToServe, and /de2api/templateManage/save). Attackers can manipulate staticResource names containing path traversal sequences (e.g., '../') combined with Base64-encoded content to write arbitrary files to the filesystem outside the intended directory, because the code only used '/' when extracting filenames without proper sanitization.

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 DataEase installation and versionLocate the DataEase installation directory and check for version indicators such as a version file, build properties, or query the application health/API endpoint that returns version informationAffected if The installed version is lower than 2.10.23 (e.g., 2.10.0 through 2.10.22) or if the version cannot be determined and the product is DataEase
-
Verify template management API is accessibleCheck if the /de2api/templateManage/save endpoint is exposed and reachable in the DataEase deployment (typically at the application's base URL)Affected if The endpoint responds and accepts requests, indicating the template save functionality is available
-
Confirm static resource handling is enabledInspect whether the StaticResourceServer component and template save functionality are loaded and operational in the running DataEase instanceAffected if The static resource upload/save feature is enabled and accessible to users or administrators
A DataEase installation is affected if it is version 2.10.22 or earlier and has the template save API (/de2api/templateManage/save) accessible, allowing path traversal via '../' sequences in staticResource names to write files outside the intended directory.

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 · scopedUpgrade DataEase to version 2.10.23 or later to obtain the patch that properly validates and extracts file names, preventing path traversal and arbitrary file writes.
DataEase 2.10.23
- 1. Back up your current DataEase installation and database.
- 2. Download DataEase version 2.10.23 from the official GitHub repository.
- 3. Stop the running DataEase service.
- 4. Install or upgrade to version 2.10.23 following the standard DataEase upgrade procedures.
- 5. Verify the installation by checking that the /de2api/templateManage/save endpoint is accessible and functioning correctly.
- 6. Confirm the path traversal vulnerability is resolved by testing that file saves are restricted to allowed directories.
- 7. Restart the DataEase service.
- 8. Monitor logs for any unusual file access attempts.
