CVE-2025-48147 Overview
CVE-2025-48147 is a Missing Authorization vulnerability [CWE-862] in the CryptoCloud - Crypto Payment Gateway plugin for WordPress. The flaw stems from incorrectly configured access control on plugin endpoints, allowing unauthenticated attackers to invoke functionality that should require privileged access. The vulnerability affects all plugin versions up to and including 2.1.2. Attackers can exploit the issue over the network without user interaction, targeting the integrity and availability of the payment gateway integration on affected WordPress sites.
Critical Impact
Unauthenticated attackers can reach protected plugin functions over the network, tampering with crypto payment gateway data and disrupting merchant transaction workflows.
Affected Products
- CryptoCloud - Crypto Payment Gateway WordPress plugin (cryptocloud-crypto-payment-gateway)
- All versions from n/a through 2.1.2
- WordPress sites processing cryptocurrency payments via the CryptoCloud gateway

Technical Details for CVE-2025-48147
Vulnerability Analysis
The CryptoCloud - Crypto Payment Gateway plugin exposes one or more action handlers without verifying the caller's role, capability, or nonce. This constitutes a Broken Access Control weakness classified under [CWE-862] Missing Authorization. Attackers can invoke these handlers directly through admin-ajax.php, REST API routes, or similar plugin endpoints and trigger state-changing operations. The impact is scoped to limited integrity and availability effects on the plugin's data and behavior, with no confidentiality impact observed. Because authentication is not required, exploitation attempts can be automated at scale against WordPress sites running the vulnerable plugin.
Root Cause
The root cause is the absence of capability checks such as current_user_can() and missing nonce verification via check_ajax_referer() or wp_verify_nonce() on plugin-registered actions. Without these guards, WordPress does not enforce authorization before executing the underlying callbacks. Any request that reaches the handler path is treated as legitimate, regardless of the requester's identity.
Attack Vector
Exploitation occurs remotely over HTTP or HTTPS against the WordPress site hosting the plugin. An unauthenticated attacker crafts a request to the exposed plugin endpoint and supplies parameters that trigger the vulnerable action. Because no privileges or user interaction are required, mass scanning and drive-by exploitation are practical. The affected functionality relates to CryptoCloud payment gateway configuration or transaction handling, which can be manipulated to disrupt payment processing.

Detection Methods for CVE-2025-48147
Indicators of Compromise
- Unauthenticated POST or GET requests to plugin endpoints under wp-admin/admin-ajax.php referencing CryptoCloud actions
- Requests to plugin REST routes containing cryptocloud without an authenticated session cookie or valid nonce
- Unexpected modifications to CryptoCloud plugin settings or transaction records in the WordPress database
Detection Strategies
- Inspect web server access logs for anomalous request patterns targeting the CryptoCloud plugin's action names and REST endpoints.
- Compare the plugin version reported in wp-content/plugins/cryptocloud-crypto-payment-gateway/ against 2.1.2 and flag any installations at or below that version.
- Alert on state-changing HTTP requests to plugin endpoints from IP addresses that have not authenticated to wp-login.php.
Monitoring Recommendations
- Enable WordPress audit logging to capture plugin option changes and payment gateway configuration edits.
- Monitor outbound webhook traffic from the site to the CryptoCloud API for unexpected callback modifications.
- Track EPSS scoring changes for CVE-2025-48147 to prioritize patch cycles as exploitation likelihood evolves.
How to Mitigate CVE-2025-48147
Immediate Actions Required
- Update the CryptoCloud - Crypto Payment Gateway plugin to a version later than 2.1.2 as soon as the vendor releases a fix.
- If no patched version is available, deactivate and remove the plugin from production WordPress instances processing payments.
- Rotate any CryptoCloud API credentials configured in the plugin to invalidate values that may have been exposed to tampering.
Patch Information
The vulnerability affects CryptoCloud - Crypto Payment Gateway up to and including 2.1.2. Consult the Patchstack Vulnerability Report for the current fixed version and vendor advisory status. Apply updates through the WordPress plugin manager or via WP-CLI once a patched release is published.
Workarounds
- Restrict access to wp-admin/admin-ajax.php and plugin REST routes at the web application firewall layer to block unauthenticated requests targeting CryptoCloud actions.
- Disable the CryptoCloud payment method in checkout configuration until a patched plugin version is deployed.
- Enforce IP allowlisting for administrative and payment gateway endpoints where operationally feasible.
