sweetalert2 versions 10.16.10 and up until 11.0.0 are vulnerable to hidden functionality that was introduced by the maintainer. The package outputs audio and/or video messages that do not pertain to the functionality of the package and is not included in versions 10.0.0 - 10.16.9.

Workaround

Use a version 10.0.0 - 10.16.9 of the package until the maintainer releases a fix.
