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::RAWHTML 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 RAWHTML functionality where it is not required.

Impact The create and store endpoints of the Quick Creation Command feature did not enforce any authorization check. An authenticated Sharp user without create permission on a given entity could bypass the authorization layer and either retrieve the creation form or submit new records for that entity, as long as it had a Quick Creation Command handler configured.

Patches Yes. The fix is included in version 9.22.3. Users should upgrade to that version or later.

Workarounds Remove or disable Quick Creation Command handlers (quickCreationCommandHandler()) on any entity list where unauthorized access is a concern, until an upgrade is possible.
