CVE-2026-110772
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.
Does this matter?
Lower severity and a low EPSS score (0.27%). Track it; it rarely justifies an emergency change on its own.
Description

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.
