## Affected

- stellarwp The Events Calendar: through 6.15.13

## Description

The The Events Calendar plugin for WordPress is vulnerable to unauthorized access due to a missing capability check on the 'start_migration', 'cancel_migration', and 'revert_migration' functions in all versions up to, and including, 6.15.13. This makes it possible for authenticated attackers, with subscriber level access and above, to start, cancel, or revert the Custom Tables V1 database migration, including dropping the custom database tables entirely via the revert action.
