Hi Alexander,

Thank you for the feedback. We only considered release branches for the
affected versions.

To fix this, the CVE record has been updated to take into account
development versions and release candidates:

      Versions:  from 5.41.0 through 5.41.10
                 from 5.39.0 before 5.40.2-RC1
                 from 5.33.1 before 5.38.4-RC1

Best,
