CVE-2025-8507Public exploitNetwork attack vector

Reflected XSS via unsanitized function filters

Published Aug 3, 2025 · Updated Aug 4, 2025

Reflected XSS in Portábilis i-Educar 2.9 allows remote authenticated users to execute script in a victim's browser via crafted filters. The /intranet/educar_funcao_lst.php endpoint reflects the nm_funcao and abreviatura values into its response without validation or sanitization. An authenticated attacker must induce another user to open the crafted request; successful exploitation runs script in that user's browser context.
