CVE-2025-23534
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 · uneditedMissing Authorization vulnerability in Mark Winiarski WPLingo wplingo allows Exploiting Incorrectly Configured Access Control Security Levels.This issue affects WPLingo: from n/a through <= 1.1.2.
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 confidenceWPLingo WordPress plugin versions up to 1.2.1 contain a missing authorization vulnerability allowing attackers to exploit incorrectly configured access control security levels. The plugin fails to properly validate user permissions before allowing access to certain functionality, potentially enabling unauthorized users to perform actions they should not have access to.

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.
-
Check installed WPLingo plugin versionIn WordPress admin, go to Plugins > Installed Plugins and locate WPLingo. The version number is displayed below the plugin name. Alternatively, check the main plugin file header in wp-content/plugins/wplingo/ for the 'Version' comment.Affected if The installed version is 1.2.1 or lower (no version specified after 1.2.1 indicates the fix may not be applied).
-
Identify users with subscriber-level accessGo to Users > All Users in WordPress admin. Review the role column for any users assigned the Subscriber role or custom roles with limited capabilities.Affected if Any user with a low-privilege role (Subscriber, Contributor, or custom role) exists and could potentially access restricted plugin functions if the vulnerability is present.
-
Inspect plugin PHP files for capability checksExamine the main plugin files (typically wplingo.php or class files in includes/ directory) for calls to WordPress functions like current_user_can, user_can, or capability checks before executing sensitive operations.Affected if Plugin code lacks current_user_can() calls or similar permission validation before performing administrative or sensitive actions.
-
Verify nonce validation on plugin AJAX actionsSearch plugin PHP files for AJAX action handlers (wp_ajax_ and wp_ajax_nopriv_ hooks). Check if these handlers include nonce verification using check_ajax_referer or wp_verify_nonce.Affected if AJAX endpoints registered with wp_ajax_nopriv_ exist, or AJAX handlers lack nonce validation, allowing unauthenticated or unauthorized access.
-
Test access to admin-only plugin functionsUsing a low-privilege user account (Subscriber role), attempt to access plugin admin pages or send direct requests to plugin AJAX endpoints. Observe whether requests are blocked or processed.Affected if Low-privilege users can access administrative plugin functions or execute actions that should require Administrator or Editor privileges.
If the WPLingo plugin version is 1.2.1 or lower AND low-privilege users can access sensitive plugin functions without proper capability checks, the environment is affected by this missing authorization vulnerability.

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 dataApply the latest available patch or update to WPLingo version 1.2.1 or later. If no update exists, implement proper WordPress capability checks (current_user_can) and nonce validation on all sensitive plugin functions, and restrict access to admin-only functions.
