CVE-2026-110772 Details
Description
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.
A missing authorization vulnerability has been identified in the Sure personal finance application, specifically in versions 0.7.0 through 0.7.6-alpha.6. The issue resides within the Transactions::BulkUpdatesController#create action, where account sharing permissions can be bypassed. This vulnerability allows authenticated family members with read-only or no share to submit arbitrary entry IDs and modify transaction details such as dates, names, notes, categories, merchants, and tags. As a result, this could lead to corruption of budgets and financial reports.
The vulnerability can be fixed by adding an account permission check to the bulk update process, ensuring that only entries from accounts the user can write to are modified. This adjustment should be made in the Transactions Bulk Updates Controller, specifically in the create action.
