CVE-2025-8787
The manipulation of the argument Registro de atividades/Conteúdos results in cross site scripting.
Does this matter?
Lower severity and a low EPSS score (0.35%). Track it; it rarely justifies an emergency change on its own.
Description
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 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."
