Description

Sharp is a content management framework built for Laravel as a package. From version 9.0.0 to before version 9.22.3, 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. This issue has been patched in version 9.22.3.
