Security readout for executives and security teams
Plain-English summary
CVE-2026-49867 is a stored cross-site scripting flaw in DataEase before 2.10.23. An authenticated user could store scriptable SVG content as a template static resource, causing same-origin script execution when another user loads it. This is business-relevant where DataEase is shared across teams or handles sensitive dashboards.
Executive priority
Prioritize remediation during the next normal security patch window, faster for multi-user or internet-accessible DataEase environments. The issue is not presented as actively exploited, but same-origin stored XSS can support account abuse and dashboard data exposure.
Technical view
DataEase accepted TemplateManageRequest.staticResource content through template save or decompression paths and wrote Base64-decoded SVG files under /de2api/static-resource/ without validating extension, MIME type, decoded bytes, or SVG scriptability. The vendor states version 2.10.23 fixes the issue.
Likely exposure
Exposure is limited to DataEase deployments running versions earlier than 2.10.23. Risk is higher where non-admin authenticated users can create, import, or manage templates and where privileged users regularly view shared template resources.
Exploitation context
The sources do not show active exploitation, and this CVE is not listed as KEV in the provided bundle. Exploitation requires an authenticated user and victim interaction: another user must load the stored same-origin resource.
Researcher notes
The advisory attributes the flaw to missing validation around stored SVG static resources. The provided evidence identifies the affected product, fixed version, vulnerable data path, and same-origin XSS impact, but does not include exploitation-in-the-wild evidence.
Mitigation direction
- Upgrade DataEase to version 2.10.23 or later.
- Review the DataEase advisory and release notes before deployment.
- Restrict template creation and import privileges to trusted users.
- Remove or review untrusted template static resources, especially SVG files.
- Monitor DataEase activity for unusual template or static-resource changes.
Validation and detection
- Inventory all DataEase instances and confirm their running versions.
- Verify affected instances are upgraded to 2.10.23 or later.
- Review roles allowed to save or import templates.
- Check for recently added static resources from untrusted accounts.
- Confirm vendor guidance is reflected in change-management records.

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
