CVE-2025-9105Public exploitNetwork attack vector

Stored script execution via unsanitized lesson-plan fields

Published Aug 18, 2025 · Updated Aug 18, 2025

Stored XSS in Portábilis i-Diário 1.5.0 and earlier allows remote authenticated users to inject scripts through lesson-plan fields. The lesson-plan endpoint stores Parecer, Conteúdos, and Objetivos values without adequate validation or sanitization and executes injected markup when Histórico is viewed. A user with access to save those fields must plant the payload, and another user's visit triggers script execution in that user's browser.
