3D FlipBook - Security patch urgently needed!

Wordfence is alerting me to a critical vulnerability for 3D Flipbook up to and including 1.16.16. Here is a detailed description of the vulnerability:

"The 3D FlipBook – PDF Embedder, PDF Flipbook Viewer, Flipbook Image Gallery plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 1.16.16. This makes it possible for unauthenticated attackers to extract sensitive user or configuration data."

When will this be patched?
