Gallery Plugin for WordPress – Envira Photo Gallery <= 1.11.0 - Missing Authorization to Authenticated (Contributor+) Gallery Conversion

The Gallery Plugin for WordPress – Envira Photo Gallery plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the '/envira-convert/v1/bulk-convert' REST API endpoint in all versions up to, and including, 1.11.0. This makes it possible for authenticated attackers, with contributor-level access and above, to convert galleries to Envira galleries.
