code16 Sharp is a Laravel-based framework for building content-management and administrative interfaces. Versions before 9.22.5 contain a stored cross-site scripting vulnerability in `SharpEditorFormField`: attacker-controlled content bearing the `data-html-content` attribute can bypass HTML sanitization and preserve executable markup, which may execute when another user views the stored content. The vendor identifies version 9.22.5 as patched; applications that intentionally enable `SharpFormEditorField::RAW_HTML` must continue to sanitize editor content themselves.
As a workaround, applications should sanitize all editor content before storing or rendering it, for example with Symfony HtmlSanitizer, and disable RAW_HTML functionality where it is not required.
