Title

Flowintel Missing Authorization Allows Regular API Users to View Other Users’ Task Assignments

Summary

Affected versions of Flowintel expose the /my_assignment/user API endpoint to any authenticated API user. The endpoint accepts a user_id parameter identifying the user whose assignments should be returned, but previously had no role restriction beyond general API authentication. As a result, a lower-privileged authenticated user could potentially query another user’s assignment information by supplying that user’s identifier. The fix changes: method_decorators = [api_required] to: method_decorators = [admin_or_org_admin_required, api_required] so only administrators or organization administrators can perform cross-user assignment queries. Version impacted =>3.3.0

Severity

5.3 (Medium)

GHSA-49JG-8R6H-H4R7

Vulnerability from github – Published: 2026-08-27 18:32 – Updated: 2026-08-27 18:32

Details

As a result, a lower-privileged authenticated user could potentially query another user’s assignment information by supplying that user’s identifier.

The fix changes:

method_decorators = [api_required]

to:

method_decorators = [admin_or_org_admin_required, api_required]

so only administrators or organization administrators can perform cross-user assignment queries.

Version impacted =>3.3.0

Severity

5.3 (Medium)
