FlowIntel up to version 3.3.0 contains a server-side request forgery (SSRF) vulnerability in the external reference URL probe functionality in app/case/task.py. An attacker who can submit an external reference URL can cause the application server to issue an HTTP HEAD request to an attacker-specified destination. Due to insufficient validation of the URL scheme and resolved destination address, affected versions may allow requests to loopback, link-local, private, reserved, or other restricted network resources, potentially enabling interaction with internal services or cloud metadata endpoints from the server's network context.

Affected versions of Flowintel expose the /myassignment/user API endpoint to any authenticated API user. The endpoint accepts a userid 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:

methoddecorators = [apirequired]

to:

methoddecorators = [adminororgadminrequired, apirequired]

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