CVE-2025-62421 — DataEase is a data visualization and analytics platform

Medium CVSS 5.5

DataEase is a data visualization and analytics platform. In DataEase versions through 2.10.13, a stored cross-site scripting vulnerability exists due to improper file upload validation and authentication bypass. The StaticResourceApi interface defines a route upload/{fileId} that uses a URL path parameter where both the filename and extension of uploaded files are controllable by users. During permission validation, the TokenFilter invokes the WhitelistUtils#match method to determine if the URL path is in the allowlist. If the requestURI ends with .js or similar extensions, it is directly deemed safe and bypasses permission checks. This allows an attacker to access "upload/1.js" while specifying arbitrary file extensions, enabling the upload of HTML files containing malicious JavaScript. The vulnerability is fixed in version 2.10.14. No known workarounds exist.

Cross-site scripting and unsafe browser output

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Trace reflected, stored, and DOM-derived untrusted values into HTML, attributes, URLs, styles, scripts, and client-side template sinks.
  • Identify affected origins, authenticated user roles, sensitive browser capabilities, and where content is shared across tenants.
  • Review framework escaping, rich-text sanitization, legacy templates, and client-side rendering paths.

Remediate safely

  • Use context-aware framework output encoding and safe DOM APIs; keep untrusted data out of executable contexts.
  • Sanitize intentionally supported markup with a maintained allowlist policy and validate URLs and attributes separately.
  • Update affected rendering components and add tests for every output context using inert sentinel markup.
