CVE-2026-50007 actualbudget CVE debrief

Who should care

Users of the Actual open-source personal finance application, particularly those who have shared access to budget files, should be aware of this vulnerability and ensure they are using version 26.7.0 or later to prevent unauthorized file management actions. Affected operators, platform administrators, vulnerability management teams, and security teams should review and act on this vulnerability.

Technical summary

The vulnerability exists due to a missing authorization check in the requireFileAccess function, which treats ordinary shared access as sufficient for file-management operations that should be restricted to the file owner or an administrator. This allows a non-owner shared user to call file-management endpoints intended for higher-privilege users, including /delete-user-file, /reset-user-file, and /user-create-key. The issue is fixed in version 26.7.0.

• Review compensating controls for exposed systems while remediation is scheduled and verified
