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 the wc-peach-payments-gateway WordPress plugin allows attackers to exploit incorrectly configured access control security levels. The plugin fails to properly validate user permissions before allowing access to certain administrative or sensitive functions, 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.
-
Verify Peach Payments plugin is installedNavigate to WordPress admin dashboard > Plugins, or check the wp-content/plugins directory for a folder containing 'peach-payments' or 'wc-peach-payments-gateway'.Affected if The plugin is present in the WordPress installation
-
Check installed plugin versionIn WordPress admin, go to Plugins > Installed Plugins, find the Peach Payments Gateway plugin, and note the version number displayed under the plugin name. Alternatively, open the main plugin PHP file (e.g., wc-peach-payments-gateway.php) and read the 'Version' header in the plugin comment block.Affected if The installed version is older than the patched version containing the authorization fix
-
Identify exposed sensitive functionsReview the plugin directory for PHP files containing AJAX handlers, admin_menu actions, or REST API endpoints. Look for functions that perform administrative or financial operations (e.g., order processing, settings updates, refund handling) without current_user_can() or capability checks.Affected if The plugin contains administrative actions or sensitive functions that lack permission validation checks
-
Test for unauthorized access to admin actionsUse a low-privilege user account (e.g., Subscriber role) to attempt access to plugin admin pages or trigger plugin-specific actions via direct URL access or AJAX calls. Inspect the HTTP response to see if the action executes without a permission error.Affected if Actions execute successfully and return expected results rather than a 403 error or 'You do not have permission' message
A user is affected if the Peach Payments Gateway plugin is installed and lacks proper capability checks on sensitive administrative functions, allowing unauthorized users to access them.
