CVE-2025-15043
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedThe 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.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceThe Events Calendar plugin for WordPress lacks capability checks on three migration-related functions (start_migration, cancel_migration, revert_migration), allowing any authenticated user with subscriber-level access to manipulate the Custom Tables V1 database migration process, including the destructive ability to drop custom database tables entirely via the revert action.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Confirm Events Calendar plugin is installedNavigate to WordPress admin > Plugins and locate 'The Events Calendar' or check via wp-cli: wp plugin list --name='the-events-calendar'Affected if Plugin is installed and active
-
Check installed plugin versionView plugin details in WordPress admin or use: wp plugin get the-events-calendar --format=jsonAffected if Version falls within unpatched range (compare to vendor release notes)
-
Verify user registration is disabledGo to WordPress Settings > General > 'Membership' and uncheck 'Anyone can register', or check via wp-cli: get_option('users_can_register')Affected if User registration is enabled (value = 1)
-
Identify subscriber-level user accountsUse wp-cli: wp user list --role=subscriber --format=count or check WordPress Users admin panel for users with Subscriber roleAffected if Any subscriber-level accounts exist on the site
-
Check if Custom Tables V1 migration feature is activeReview plugin settings for Custom Tables V1 migration status, or check database for migration-related options: wp option get tribe_events_custom_tables_v1_migration_statusAffected if Custom Tables V1 migration is enabled or in progress
A site is affected if the Events Calendar plugin is installed, user registration is open OR subscriber accounts exist, and the vulnerability is unpatched in that version.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataUpdate the plugin to a patched version when available. Until then, disable user registration or audit subscriber-level accounts, as this vulnerability allows low-privileged users to destroy database tables.
