In plain words

The Drupal Security Team has marked this project unsupported because it has a known security issue that the maintainer has not fixed. The advisory does not explain what an attacker could do or under which conditions, and it lists no fixed version.

Am I affected?

Look for drupal/cacheflush in composer.lock and note its installed version. The advisory gives no affected version range and names no configuration, feature or database conditions, so it does not provide enough detail to determine whether a particular version is affected.

What to do

There is no fixed release yet. Read the advisory for a workaround, and watch drupal/cacheflush for a new version.
