CVE-2025-6042
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 Lisfinity Core - Lisfinity Core plugin used for pebas® Lisfinity WordPress theme plugin for WordPress is vulnerable to privilege escalation in all versions up to, and including, 1.4.0. This is due to the plugin assigning the editor role by default. While limitations with respect to capabilities are put in place, use of the API is not restricted. This vulnerability can be leveraged together with CVE-2025-6038 to obtain admin privileges.
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 Lisfinity Core WordPress plugin assigns the editor role by default to users, creating a privilege escalation vector. Although capability limitations exist, the plugin fails to restrict API access, allowing unprivileged users to potentially perform actions beyond their intended permissions. This can be chained with CVE-2025-6038 to achieve full administrator access.

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.
-
Verify Lisfinity Core plugin is installedIn WordPress admin, go to Plugins > Installed Plugins and look for 'Lisfinity Core' or check the plugins directory via file system for /wp-content/plugins/lisfinity-core/Affected if The plugin is present in the WordPress installation
-
Check installed plugin versionIn WordPress admin Plugins page, find Lisfinity Core and note the version number displayed, or inspect the main plugin file header for 'Version:' fieldAffected if Version is 1.4.0 or lower (versions beyond 1.4.0 contain the fix)
-
Confirm WordPress user registration is enabledIn WordPress admin, go to Settings > General and check 'Anyone can register' setting, or query the database: SELECT option_value FROM wp_options WHERE option_name = 'users_can_register'Affected if User registration is enabled (value = 1)
-
Identify unexpected editor-level usersQuery users with editor role: In WordPress admin under Users > All Users, filter by 'Editor' role, or query: SELECT user_id, meta_value FROM wp_usermeta WHERE meta_key = 'wp_capabilities' AND meta_value LIKE '%editor%'Affected if There are editor users who did not receive that role intentionally from an administrator
A user is affected if Lisfinity Core plugin is installed with version 1.4.0 or lower AND WordPress user registration is enabled, allowing potential privilege escalation via unintended editor role assignment and unrestricted API access.

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 version beyond 1.4.0 that removes the default editor role assignment and implements proper API access controls with authentication checks. Until a fix is available, disable the plugin or restrict user registration.
