CVE-2026-102755 — DataEase Datasource/Dataset Folder Name Stored Cross-Site Scripting

DataEase is an open source data visualization and analysis tool. Prior to 2.10.26, authenticated users with folder creation permission can store HTML-bearing names through datasource/createFolder or datasetTree/save. The datasource and dataset Move to dialogs in core/core-frontend/src/views/visualized/data/datasource/form/CreatDsGroup.vue and core/core-frontend/src/views/visualized/data/dataset/form/CreatDsGroup.vue read the stored name from a node title attribute and assign search-highlighted content to innerHTML. When another user opens a Move to dialog and types in its search box, attacker-controlled JavaScript can execute in the victim's DataEase session. This issue is fixed in version 2.10.26.

Who exploits it and how urgent it is

A 0–100 score combining confirmed exploitation, ransomware and APT use, public exploits, EPSS and severity.

No exploitation signal in the sources consulted so far.
How the score was calculated
  • Technical severity (medium)+3
  • CISA SSVC: exploitation "poc"+5

The score orders the patch queue; it does not replace your asset context (internet exposure, criticality, compensating controls).

Triage

Is it exploited, how likely is exploitation, what does it touch, and how severe do the sources call it.

Remediation

Fixes and mitigations documented by the sources — linked to the original advisory.

No fix documented by the sources we poll. That does not mean none exists: check the vendor advisory.

First 24 hours

Ordered from the record’s own fields — exposure first, because you cannot patch what you have not found. A rule-generated starting point.

  1. Identify exposed assets running the affected vendor/product/version combinations (Dataease Dataease).
  2. No fix documented in the sources: reduce exposure and monitor the vendor advisory.
  3. Exploitation requires user interaction: tighten email/web filtering and warn affected users.
  4. Search available logs for exploit probes matching the vulnerability class (cross-site scripting), errors and authentication anomalies.
