CVE-2024-37883Network attack vector

Deleted-card disclosure via missing access filters

Published Jun 14, 2024 · Updated Aug 2, 2024

Improper access control in affected Nextcloud Deck releases allows remote authenticated users to read deleted-card content. Card and activity queries failed to exclude soft-deleted cards, leaving their comments and attachments retrievable through authenticated Deck requests. The attacker must already have access to the affected board; the documented consequence is disclosure of deleted content, not modification or service interruption.
