Vendor statement (Portabilis)

This reflected XSS in the content autocomplete (/conteudos, parameter filter[by_description]) has been fixed in i-Diário.

The searched term is now rendered escaped in the autocomplete widget, and the content tags are rendered through output-escaped templates, so an injected payload is displayed as inert text instead of being executed.

The fix is available in the project's public repository, in commit https://github.com/portabilis/i-diario/commit/d076c112b45e3b3e41cbe11de27949b491d922c2

Recommended action: update to a current release of i-Diário.
