CVE-2025-8541Public exploitNetwork attack vector

Authenticated browser script execution via unsanitized nome

Published Aug 5, 2025 · Updated Aug 7, 2025

Stored XSS in Portábilis i-Educar 2.10 allows remote authenticated users to execute scripts in another user's browser via nome input. The public_uf_cad.php endpoint stores the nome value without sanitization, and public_uf_lst.php renders it so the browser executes the payload. High-privilege access is required to save the value, and another user must load the listing page; the script can alter displayed content or access browser-session data.
