Description

There looks to be a bug related to issue #6411 affecting Intrusion-sets and Malware. Unfortunately, I don't have enough data in my test environment to test threat actor/tools etc etc.

Environment

OpenCTI 6.1.8

Reproducible Steps

Steps to create the smallest reproducible scenario:
Using data from the Alienvault Connector...
Arsenal -> Malware -> Knowledge -> Indicators
Select all indicators using the select all check box
Update entities -> Add -> Label -> test (or whatever label you want to add) -> Update
Confirm in Launch a background task window that only a small number of elements are selected -> Launch
Go to background task page to see that target entities has changed to all indicators

These steps are also repeatable with Intrusion-Sets

Expected Output

Only the selected entities should be having labels added.

Actual Output

All entities are having labels added.

Additional information

This bug ruined my night.
