Sharp Missing Authorization Check in Quick Creation Command Endpoints
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.
