RISK

Why deck_update_card is rated Medium

This tool modifies existing data (a Deck card) in a reversible manner without deletion or destruction. It does not execute arbitrary code, trigger financial transactions, or permanently remove data. The blast radius is contained to card metadata/content within Nextcloud's Deck application, making it Write rather than Execute or higher severity.

From the tool's definition Tool name 'deck_update_card' and description 'Update an existing Deck card' explicitly indicates modification of data. The description emphasizes selective field changes while preserving unchanged data, which is characteristic of reversible write operations.
