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 · unedited
ProjectsAndPrograms school-management-system is vulnerable to Stored Cross‑Site Scripting (XSS) in multiple attributes of students and teachers objects. An authorized attacker (e.g., a teacher or administrator) can inject malicious JavaScript that is subsequently executed in other users’ browsers. Critically, when chained with CVE‑2025‑11661, which allows unauthenticated access to backend endpoints, this vulnerability can be exploited by a remote attacker without privileges to inject and execute arbitrary JavaScript. The maintainers were notified early about this vulnerability but did not provide details regarding affected versions. The version corresponding to commit 6b6fae5 was tested and confirmed vulnerable; other versions were not tested and may also be affected.

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 confidence

Stored Cross-Site Scripting (XSS) vulnerability in the ProjectsAndPrograms school-management-system allows authorized users (teachers/administrators) to inject malicious JavaScript into student and teacher object attributes. When chained with CVE-2025-11661, unauthenticated remote attackers can exploit this flaw. The malicious payload persists in the database and executes in victim browsers when other users view the affected records.

MitigationImplement robust input validation and output encoding for all student and teacher attributes, with particular focus on fields that accept user-supplied content. Sanitize existing database records to remove any stored payloads. Consider implementing Content Security Policy headers.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify the application and its installed version
    Locate the school-management-system application directory or check the software inventory/manifest file that lists the installed version number. Compare your version against any known version releases.
    Affected if The application is installed and your version has not received security updates for stored XSS vulnerabilities.
  2. Verify student/teacher record input functionality exists
    Access the application interfaces that allow creating or editing student and teacher profile records. These are typically found in admin or staff control panels under sections labeled 'Students', 'Teachers', 'Staff', or 'Users'.
    Affected if The application contains editable student or teacher record forms where user-supplied data can be saved to the database.
  3. Test for reflected output of stored data
    Create or edit a test student/teacher record using the application interface. Enter a harmless test string containing HTML characters (such as <script>alert(1)</script> or <img src=x onerror=alert(1)>). Save the record, then view the same record as a different user or in a different view context.
    Affected if The entered characters render as unescaped HTML or JavaScript when you view the saved record, indicating missing output encoding.
  4. Inspect database for unsanitized stored content
    Query the database tables that store student and teacher records (commonly named students, teachers, staff, users, or profiles). Look for records containing raw HTML tags, script elements, or event handler attributes in name, description, or other text fields.
    Affected if The database contains records with unescaped HTML or script tags in student or teacher fields, indicating the application stores input without sanitization.
  5. Check for missing output encoding in application source
    Examine the application code that renders student and teacher data in views or templates. Look for places where database values are inserted into HTML without using encoding functions (such as htmlspecialchars, escape, or equivalent sanitization methods).
    Affected if The application renders student/teacher field values directly into HTML without applying context-aware encoding.

You are affected if the school-management-system is installed and its student/teacher record views display stored content without output encoding, allowing embedded JavaScript to execute when records are viewed.
