CVE-2026-50007 actualbudget CVE debrief

CVE-2026-50007 is a high-severity vulnerability in the Actual open-source personal finance application. Prior to version 26.7.0, a missing authorization issue allows a shared user with user_access on a budget file to perform owner-only file management actions. This issue is fixed in version 26.7.0. 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.

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.

Defensive priority

  • Monitor file management actions for suspicious activity
  • Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up
  • Review compensating controls for exposed systems while remediation is scheduled and verified
  • Check relevant monitoring, detection, and logs for exposed assets that need extra review
  • Track exceptions, retest remediated assets, and close the item only after evidence is documented
