Improper access control in Nextcloud Deck 0.8.0 allowed an attacker to reshare boards shared with them with more permissions than they had themselves.
The product does not preserve permissions or incorrectly preserves permissions when copying, restoring, or sharing objects, which can cause them to have less restrictive permissions than intended.
