Andrushika opened a new issue, #76512:
URL: https://github.com/apache/airflow/issues/76512

   ### Under which category would you file this issue?
   
   Airflow Core
   
   ### Apache Airflow version
   
   main and v3-4-test (adb86572b9)
   
   ### What happened and how to reproduce it?
   
   #76012 restores masked values when a user saves a Variable from the UI edit 
form. The form shows the redacted value, so each secret arrives as `***`. 
`merge()` from the secrets masker then puts the stored secret back.
   
   For a list, `merge()` matches the items by position. If the user deletes or 
reorders an item in a list that holds secrets, an item gets the secret of a 
different item. No error shows.
   
   The stored value:
   
   ```json
   {"users": [{"name": "alice", "password": "A-secret"}, {"name": "bob", 
"password": "B-secret"}]}
   ```
   
   The user deletes alice in the edit form and saves. The stored value becomes:
   
   ```json
   {"users": [{"name": "bob", "password": "A-secret"}]}
   ```
   
   If the user swaps the two items instead, bob gets `A-secret` and alice gets 
`B-secret`.
   
   
   ### How to reproduce
   
   I reproduced it with `merge()`, the function that `PATCH 
/api/v2/variables/{key}` calls (`services/public/variables.py`). I did not run 
it through the UI.
   
   ```python
   from airflow_shared.secrets_masker.secrets_masker import (
       DEFAULT_SENSITIVE_FIELDS,
       _secrets_masker,
       merge,
       redact,
   )
   
   _secrets_masker().sensitive_variables_fields = list(DEFAULT_SENSITIVE_FIELDS)
   
   stored = {"users": [{"name": "alice", "password": "A-secret"}, {"name": 
"bob", "password": "B-secret"}]}
   shown = redact(stored, "creds")
   edited = {"users": [u for u in shown["users"] if u["name"] != "alice"]}
   
   print(merge(edited, stored, "creds"))
   # {'users': [{'name': 'bob', 'password': 'A-secret'}]}
   
   ### What you think should happen instead?
   
   A `***` should only take back the secret of the same item. If I read 
`merge()` right, it has no way to know which item is the same once the list 
changes, so I am not sure what the best rule is. Keeping the `***` for items 
that moved would at least not give one item the secret of another.
