CVE-2026-81819 · Severity: info · Published 2026-08-27

Flowintel, an intelligence and case management platform, exposed an API endpoint that allowed any authenticated user to view other users' task assignments. By providing another user's identifier, a lower-privileged user could retrieve sensitive assignment information they should not have access to. The vulnerability has been patched by restricting the endpoint to administrators and organization administrators only.

## Technical details

The /my_assignment/user API endpoint in Flowintel versions ≥3.3.0 was protected only by general API authentication (api_required decorator), lacking role-based access control. An attacker could exploit this by making an authenticated API request with a user_id parameter pointing to another user's identifier to retrieve that user's task assignments. The vulnerability required prior API authentication but no other preconditions. The fix adds the admin_or_org_admin_required decorator to restrict endpoint access to administrative users only. The patch was deployed in commit 10ec32e7baa0fa12ffb83bec36d1b4749a428b5c on August 18, 2026.
