In both cases this means that `item` could be an `int` or a `str`.

#### Possibly `None` { #possibly-none }

You can declare that a value could have a type, like `str`, but that it could also be `None`.

In Python 3.6 and above (including Python 3.10) you can declare it by importing and using `Optional` from the `typing` module.

   * delete the file and create a directory in its place, but this leads a race condition which can
   * be exploited to create security vulnerabilities, especially when executable files are to be
   * written into the directory.

   * <p>This method assumes that the temporary volume is writable, has free inodes and free blocks,
   * and that it will not be called thousands of times per second.

### CVE-2024-5321: Incorrect permissions on Windows containers logs

A security issue was discovered in Kubernetes clusters with Windows nodes
where BUILTIN\Users may be able to read container logs and NT
AUTHORITY\Authenticated Users may be able to modify container logs.

**Affected Versions**:
  - kubelet <= 1.27.15
  - kubelet <= 1.28.11
  - kubelet <= 1.29.6
  - kubelet <= 1.30.2 

**Fixed Versions**:

        scoreUpdater.addScoreBooster(booster3);

        // Clear execution order before test
        PriorityTrackingBooster.clearExecutionOrder();

        scoreUpdater.execute();

        // Boosters should be executed in priority order (3, 2, 1)
        List<Integer> executionOrder = PriorityTrackingBooster.getExecutionOrder();
        assertEquals(3, executionOrder.size());
        assertEquals(Integer.valueOf(3), executionOrder.get(0));
