CVE-2026-3110Network attack vector

Unauthenticated user-data disclosure via enumerable course IDs

Published Mar 16, 2026 · Updated Mar 16, 2026

IDOR in Educativa Campus Virtual 14.05.00-35 allows remote attackers to read enrolled users' personal data through a crafted URL. The admin_usuarios.cgi export endpoint accepts a user-controlled wid_cursoActual value and returns the referenced course roster without enforcing access control. No authentication or user interaction is required, and enumerating course IDs exposes usernames, names, email addresses, and phone numbers without altering data.
