## Overview

A security flaw has been discovered in Portabilis i-Diario up to 1.5.0. The affected element is an unknown function of the file /registros-de-conteudos-por-disciplina/ of the component Registro das atividades. The manipulation of the argument Registro de atividades/Conteúdos results in cross site scripting. The attack may be launched remotely. The exploit has been released to the public and may be used for attacks. The patch is identified as 821342cd8d952e8bd214cb16145da785a92f5681. A patch should be applied to remediate this issue. The vendor confirms: "Audited values shown on that screen are now sanitized on output: only a minimal allowlist of basic formatting tags is kept and all attributes are stripped, so injected <script> or event-handler markup is removed and displayed as inert text."

## Affected
