Vendor statement (Portabilis)

This stored XSS has been fixed in i-Diário.

The values submitted in the knowledge-area content record endpoint (the activity register and content fields) were later rendered on the record's History screen. 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.

The fix is available in the project's public repository, in commit https://github.com/portabilis/i-diario/commit/821342cd8d952e8bd214cb16145da785a92f5681

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