CVE-2025-9104Public exploitNetwork attack vector

Stored XSS via unsanitized lesson-plan fields

Published Aug 18, 2025 · Updated Aug 18, 2025

Stored XSS in Portábilis i-Diário 1.0 through 1.5.0 allows remote authenticated users to run script in another user's browser. The lesson-plan additional-information endpoint stores Parecer, Objeto de Conhecimento, and Habilidades values without adequate validation or sanitization, then renders them in History. An authenticated account must save a crafted value and another user must open the affected history page, enabling actions in that user's browser context.
