CVE-2026-48889
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 · uneditedSubscriber Privilege Escalation in Amelia <= 2.3 versions.
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 · moderate confidenceThe Amelia WordPress plugin versions 2.3 and below contains a privilege escalation vulnerability allowing authenticated users with Subscriber-level permissions to elevate their privileges to higher permission levels (such as Administrator). This likely involves improper validation of user capabilities when processing certain plugin functions or AJAX actions.

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 Amelia plugin is installedIn WordPress admin, go to Plugins > Installed Plugins and look for 'Amelia' plugin, or check the plugin files in wp-content/plugins/amelia for a version fileAffected if Amelia plugin is not installed on the WordPress site
-
Check installed Amelia versionIn WordPress admin, go to Plugins > Installed Plugins and look at the version number listed under the Amelia plugin, or read the main plugin PHP file for the 'Version' header commentAffected if Version is 2.3 or lower (any version up to and including 2.3)
-
Confirm WordPress user registration is enabledGo to WordPress Settings > General > 'Membership' setting and check if 'Anyone can register' is ticked, or query the 'users_can_register' option in the wp_options tableAffected if User registration is enabled on the site
-
Identify subscriber-level users with elevated rolesGo to Users > All Users in WordPress admin and review the role column, or query wp_usermeta for users with meta_key='wp_capabilities' containing 'subscriber' but with elevated role assignmentsAffected if Any user account has Administrator or other elevated role assigned without proper authorization
-
Audit recent role changes on user accountsQuery the wp_usermeta table for recent changes to meta_value containing role changes, or review WordPress activity logs for user capability changes involving the Amelia pluginAffected if Recent unexpected role modifications exist, especially involving users who only had Subscriber role
A site is affected if Amelia plugin version 2.3 or below is installed AND WordPress user registration is enabled, allowing any authenticated subscriber to potentially escalate to Administrator privileges.

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 Amelia plugin to a version newer than 2.3. If immediate update is not possible, disable new user registration on the site and review user accounts for unauthorized privilege escalation.
