CVE-2025-47563 Overview
CVE-2025-47563 is a missing authorization vulnerability [CWE-862] affecting the villatheme CURCY woocommerce-multi-currency plugin for WordPress. The flaw impacts all versions up to and including 2.3.7. Unauthenticated attackers can access plugin functionality that is not properly constrained by access control lists (ACLs), enabling arbitrary shortcode execution against affected sites. According to the Patchstack advisory, the vulnerability allows attackers to render arbitrary WordPress shortcodes, potentially exposing content or triggering functionality intended for authenticated contexts.
Critical Impact
Unauthenticated attackers can invoke arbitrary shortcodes on vulnerable WordPress sites, leading to information disclosure and abuse of restricted plugin features.
Affected Products
- villatheme CURCY (WooCommerce Multi Currency) plugin for WordPress
- All plugin versions from n/a through <= 2.3.7
- WordPress sites running WooCommerce with the CURCY plugin installed

Technical Details for CVE-2025-47563
Vulnerability Analysis
The CURCY plugin exposes functionality through WordPress AJAX or REST endpoints without verifying the requester's capabilities. The plugin fails to enforce authorization checks before executing sensitive operations. This allows any anonymous visitor to reach code paths that should be limited to authenticated administrators or shop managers.
According to the Patchstack advisory, the specific outcome is arbitrary shortcode execution. WordPress shortcodes can invoke plugin logic, render restricted content, or reveal data intended only for logged-in users. The impact classification limits disclosure to low-confidentiality data with no direct integrity or availability effect.
Root Cause
The root cause is a missing capability check [CWE-862] in one or more plugin request handlers. The affected handler processes user-supplied input and passes it to WordPress's do_shortcode() function without validating the caller's role or nonce. This pattern violates the WordPress plugin security model, which requires current_user_can() checks and nonce verification via check_ajax_referer() or wp_verify_nonce() on state-changing or privileged endpoints.
Attack Vector
The attack requires network access only. No authentication, user interaction, or elevated privileges are needed. An attacker sends a crafted HTTP request to the vulnerable plugin endpoint on a target WordPress site running CURCY <= 2.3.7. The request supplies a shortcode string that the plugin renders server-side and returns in the response. Attackers can enumerate shortcodes registered by WooCommerce, CURCY, and other installed plugins to extract data such as private product information, user counts, or configuration details.
No verified public proof-of-concept code is published in the referenced advisory. Refer to the Patchstack advisory for CVE-2025-47563 for additional technical context.
Detection Methods for CVE-2025-47563
Indicators of Compromise
- Unauthenticated POST or GET requests to /wp-admin/admin-ajax.php referencing CURCY plugin actions from unknown source IPs.
- HTTP request bodies containing WordPress shortcode syntax such as [ and ] tokens sent to plugin AJAX endpoints.
- Anomalous spikes in AJAX response sizes suggesting shortcode rendering to unauthenticated clients.
- Presence of the CURCY plugin at version <= 2.3.7 in wp-content/plugins/woocommerce-multi-currency/.
Detection Strategies
- Inspect WordPress access logs for repeated calls to CURCY AJAX actions originating from clients without an authenticated session cookie.
- Deploy web application firewall (WAF) rules that identify shortcode payloads in request parameters targeting the plugin.
- Correlate unauthenticated admin-ajax.php requests with subsequent unusual data egress patterns.
Monitoring Recommendations
- Enable WordPress audit logging to capture AJAX and REST endpoint invocations with associated user context.
- Track plugin inventory across WordPress hosts and alert on installations of vulnerable CURCY versions.
- Forward web server logs to a centralized analytics platform to identify low-volume enumeration attempts against shortcode handlers.
How to Mitigate CVE-2025-47563
Immediate Actions Required
- Identify all WordPress sites running the CURCY plugin and confirm installed versions against the vulnerable range <= 2.3.7.
- Update the CURCY plugin to the latest version released after 2.3.7 that contains the vendor fix.
- If patching is not immediately possible, deactivate the CURCY plugin until an update can be applied.
- Review WordPress logs for prior unauthenticated access to plugin AJAX endpoints and investigate any anomalies.
Patch Information
Villatheme has addressed the missing authorization flaw in a CURCY release subsequent to 2.3.7. Refer to the Patchstack advisory for CVE-2025-47563 for the fixed version reference and download the update through the WordPress plugin dashboard or the vendor site.
Workarounds
- Restrict access to /wp-admin/admin-ajax.php at the WAF layer for unauthenticated clients where feasible.
- Block requests containing shortcode syntax in parameters targeted at CURCY endpoints using virtual patching rules from your WAF or WordPress security plugin.
- Apply the principle of least privilege to WooCommerce and CURCY configuration to limit the data reachable through shortcodes.
# Configuration example: identify vulnerable CURCY installations
grep -R "Version:" wp-content/plugins/woocommerce-multi-currency/*.php | head -n 5
# Force plugin update via WP-CLI once a fixed release is available
wp plugin update woocommerce-multi-currency --path=/var/www/html
