CVE-2025-25620
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 · uneditedUnifiedtransform 2.0 is vulnerable to Cross Site Scripting (XSS) in the Create assignment function.
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 · moderate confidenceUnifiedtransform version 2.0 contains a stored Cross Site Scripting (XSS) vulnerability in the Create assignment functionality. User-supplied input within the assignment creation process is not properly sanitized or escaped, allowing malicious JavaScript code to be stored and executed when other users view the assignment.

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 the installed version of UnifiedtransformLocate the version file, composer.json, or application metadata that contains the Unifiedtransform version number. Common locations include a version.php file, composer.json in the application root, or the application's about/admin panel.Affected if The installed version is exactly 2.0 (the affected version listed)
-
Confirm the Create assignment feature is accessibleLog into the application and navigate to the assignment creation interface. This is typically found in the academic or coursework management section of the application.Affected if The Create assignment functionality exists and is accessible to users in the application
-
Verify assignment data storage and display behaviorCreate a test assignment with a simple non-malicious test string (such as <script>test</script>) in the assignment title or description fields. Save the assignment and view it as a different user.Affected if The test string is rendered as raw HTML/JavaScript when viewed rather than being escaped or removed, indicating lack of output encoding
You are affected if the installed Unifiedtransform version is exactly 2.0, the Create assignment feature is in use, and user-supplied input in assignments is displayed without being sanitized or escaped.
Generated from the published advisory. Verify against your own configuration.
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 input validation and output encoding/escaping for all user-supplied data in the Create assignment function. Use context-appropriate encoding (HTML, attribute, JavaScript) based on where the data is rendered, and consider implementing a Content Security Policy (CSP) as a defense-in-depth measure.
