The plugin's logging endpoint is protected with a hardcoded authentication token that is identical across all installations rather than being unique per site. This allows unauthenticated remote attackers to access the endpoint via network-based requests and retrieve newsletter sending logs containing sensitive information such as recipient email addresses. No known fix is available as of the advisory publication.
