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
pwn.college is an education platform to learn about, and practice, core cybersecurity concepts in a hands-on fashion. Missing access control on rendering custom (unprivileged) dojo pages causes ability for users to create stored XSS.

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

pwn.college fails to enforce proper access controls on custom dojo page rendering, allowing unprivileged users to create and store malicious content. This missing authorization check on the page rendering functionality enables stored Cross-Site Scripting (XSS) attacks where malicious scripts are persisted and executed when other users view the compromised pages.

MitigationImplement role-based access control (RBAC) to verify user privileges before rendering custom dojo pages, ensuring only authorized users can create or modify page content that gets stored and rendered to other users.

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. Verify pwn.college installation is accessible
    Confirm the pwn.college web application is running and reachable at its expected URL
    Affected if The application is running and accessible to unprivileged users without authentication requirements for page creation.
  2. Identify available user roles and privileges
    Log into the application and enumerate the user role hierarchy - check if there are distinct privilege levels (e.g., student, instructor, admin) and whether role assignment is publicly visible or configurable
    Affected if The system defines multiple roles but does not restrict custom dojo page creation to privileged roles only.
  3. Test page creation access for unprivileged accounts
    Create a standard (non-admin) user account and attempt to create or modify a custom dojo page using the page rendering functionality
    Affected if Unprivileged users can successfully create, store, or modify page content that is persisted and rendered to other users.
  4. Inspect stored page content for lack of sanitization
    After creating a test page with script tags or HTML content, retrieve the page and examine the stored response to see if content is rendered as-is without sanitization or encoding
    Affected if The stored page content is rendered directly to other users without input sanitization, enabling stored XSS.
  5. Review application logs for authorization checks
    Examine server-side logs or code for presence of role-based access control (RBAC) checks before executing page rendering logic
    Affected if No authorization verification occurs before the page rendering function executes custom dojo page content.

A user is affected if unprivileged accounts can create or modify custom dojo pages that get stored and rendered to other users without any authorization or input sanitization checks.
