TrustExecutor
It basically means that Obtainium attempted to automatically update a app but is unsure if it actually succeeded in doing so or not. So the notification is prompting you to go check manually if the update was performed successfully or not.
Which it's actually pretty easy to check you can simply go into Obtainium and see if a app that "may have been updated" still has a update available. If it does then Obtainium likely failed to apply the update automatically. If it doesn't then Obtainium likely did it's job just fine.
