Description
Impact
Searches for sharees are performed by default on the lookup server in the Nextcloud Deck app before 1.2.7 and 1.4.2. This breaks the expectation that searches are only on the local Nextcloud server unless a global search has been explicitly chosen by the user.
Patches
It is recommended that the Nextcloud Deck App is upgraded to 1.2.7 or 1.4.2
Workarounds
None.
