CVE-2025-8545Public exploitNetwork attack vector

Stored script execution via unsanitized absence reason

Published Aug 5, 2025 · Updated Aug 7, 2025

Stored XSS in Portábilis i-Educar 2.10 allows remote authenticated users to persist script code through the nm_motivo field. The absence-reason form sends nm_motivo to educar_motivo_afastamento_cad.php without sanitization, stores it, and renders it on educar_motivo_afastamento_lst.php. High-privilege access is required to submit the value, and another user must load the listing page for the script to execute in that user's browser.
