## Affected

- Unknown Audio Player Block: from 1.1.0, fixed in 1.6.3

## Description

The Audio Player Block WordPress plugin before 1.6.3 does not validate the scheme of a user-supplied URL before using it as a link target, allowing users with the Contributor role and above to store malicious JavaScript that executes in the session of any user who later triggers the link (such as an administrator or editor reviewing the post).
