CVE-2026-1833
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 WaMate Confirm – Order Confirmation plugin for WordPress is vulnerable to unauthorized access in all versions up to, and including, 2.0.1. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with subscriber-level access and above, to block and unblock phone numbers, which should be restricted to administrators.
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 WaMate Confirm WordPress plugin lacks proper capability checks on block/unblock phone number functions, allowing any authenticated user with subscriber-level access to perform administrative actions they should not have permission to execute.

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 WaMate Confirm plugin is installedCheck the WordPress plugins directory for the wamate-confirm plugin folder, or run: wp plugin list --search='wamate*'Affected if The plugin folder 'wamate-confirm' or similar exists in wp-content/plugins/
-
Determine installed plugin versionRead the plugin header from wp-content/plugins/wamate-confirm/wamate-confirm.php (or main plugin file) to find the 'Version:' field, or run: wp plugin get wamate-confirm --field=versionAffected if Version is present but lower than 2.0.2, or version cannot be determined (indicating an older unpatched release)
-
Identify subscriber-level user accountsRun: wp user list --role=subscriber --format=count OR check the wp_users and wp_usermeta tables for users with subscriber roleAffected if Any subscriber-level users exist in the WordPress installation
-
Confirm block/unblock phone functions lack capability checksReview the plugin PHP files for block/unblock phone functions (typically in includes/ or main plugin file) and verify they do not include current_user_can() checks before executing administrative actionsAffected if The block/unblock phone number functions execute without verifying user capabilities (no current_user_can() call with appropriate capability)
User is affected if WaMate Confirm plugin is installed with a version below 2.0.2 AND subscriber-level user accounts exist in WordPress, allowing those subscribers to perform unauthorized administrative actions.
