Description OSIDB Bzimport 2026-10-14 19:01:28 UTC
Sure 0.7.0 through 0.7.6-alpha.6 contains a missing authorization vulnerability in Transactions::BulkUpdatesController#create that allows family members to bypass account sharing permissions. Authenticated members with read_only or no share can submit arbitrary entry_ids to modify other members' transaction dates, names, notes, categories, merchants and tags, corrupting budgets and reports.
