CVE-2025-66124
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 ZEEN101 Leaky Paywall leaky-paywall allows Exploiting Incorrectly Configured Access Control Security Levels.This issue affects Leaky Paywall: from n/a through <= 4.22.6.
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 confidenceMissing Authorization vulnerability in ZEEN101 Leaky Paywall plugin allows attackers to access functionality without proper authentication due to incorrectly configured access control security levels. The plugin fails to enforce proper capability checks on certain endpoints or functions, enabling unauthorized users to potentially exploit paywall features.

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 Leaky Paywall plugin is installedIn WordPress admin, go to Plugins > Installed Plugins and look for 'Leaky Paywall' by ZEEN101. Note whether it is active or inactive.Affected if The plugin is installed and active.
-
Identify the installed Leaky Paywall versionClick on the plugin name in Plugins > Installed Plugins to view the version number, or inspect the plugin file header in wp-content/plugins/leaky-paywall/plugin.php for the 'Version' field.Affected if The installed version is prior to the patched release (version 4.22.6 or later if a fix was released).
-
Check for unauthenticated access to subscriber functionsUse a tool like curl or Burp Suite to send requests to common Leaky Paywall endpoints (such as /?xml=1, /?rest_route=, or ajax handlers) WITHOUT providing authentication credentials. Inspect the HTTP response for successful data access rather than an authorization error.Affected if Requests without authentication tokens return expected subscriber content or success responses instead of 401/403 errors.
-
Inspect capability checks in plugin codeIf you have file access, search the leaky-paywall directory for calls to current_user_can, wp_get_current_user, or capability checks. Look for endpoints or functions referenced in the plugin that may lack these checks.Affected if Functions or endpoints handling sensitive paywall data are found without proper current_user_can() validation.
You are affected if the Leaky Paywall plugin is active and running a version without the authorization fix, where unauthenticated users can access restricted paywall functionality.

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 Leaky Paywall to the latest available version (if a version beyond 4.22.6 is released) to obtain vendor patches. If no patched version exists, implement WordPress capability checks at the application level or restrict access via server-side configuration until a fix is available.
