CVE-2025-47542 Overview
CVE-2025-47542 is a Cross-Site Request Forgery (CSRF) vulnerability affecting the Migaweb Simple Calendar for Elementor WordPress plugin. The flaw exists in all versions up to and including 1.6.5. An attacker can trick an authenticated user into submitting a forged request that performs unintended actions within the plugin. Exploitation requires user interaction, typically through a crafted link or malicious page. The vulnerability is tracked under CWE-352: Cross-Site Request Forgery.
Critical Impact
Successful exploitation allows attackers to perform state-changing actions in the plugin on behalf of an authenticated WordPress user without their consent.
Affected Products
- Migaweb Simple Calendar for Elementor plugin for WordPress
- All versions from n/a through 1.6.5
- WordPress sites running the simple-calendar-for-elementor plugin

Technical Details for CVE-2025-47542
Vulnerability Analysis
The Simple Calendar for Elementor plugin fails to validate the origin of state-changing HTTP requests. Sensitive plugin actions lack proper CSRF token verification, such as WordPress nonces validated with check_admin_referer() or wp_verify_nonce(). An attacker who lures an authenticated administrator or privileged user to a malicious page can force the browser to submit requests to the target WordPress site. Because the browser automatically attaches session cookies, the server processes these forged requests as legitimate. The confidentiality impact is none, but limited integrity impact is possible through unauthorized changes to plugin configuration or data.
Root Cause
The root cause is missing or insufficient anti-CSRF protection on privileged plugin endpoints. Request handlers accept authenticated requests without confirming that the request originated from a trusted context within the WordPress admin interface. This maps directly to CWE-352.
Attack Vector
Exploitation occurs over the network and requires user interaction. An attacker crafts a webpage containing an auto-submitting form or embedded request targeting a vulnerable plugin endpoint. The attacker then delivers the link through phishing, forum posts, or comment fields. When a logged-in WordPress user visits the page, the browser silently submits the request using the victim's session, triggering the unauthorized action.
No verified public proof-of-concept code is available. See the Patchstack WordPress Vulnerability Advisory for additional technical context.
Detection Methods for CVE-2025-47542
Indicators of Compromise
- Unexpected changes to Simple Calendar for Elementor plugin configuration or calendar entries
- WordPress access logs showing state-changing POST requests to plugin endpoints with external Referer headers
- Administrator sessions producing plugin modifications shortly after visiting untrusted external links
Detection Strategies
- Audit WordPress request logs for POST requests to simple-calendar-for-elementor endpoints lacking a valid nonce parameter
- Correlate administrator browsing activity with unexpected plugin configuration changes
- Deploy a Web Application Firewall (WAF) rule that inspects Referer and Origin headers on plugin admin routes
Monitoring Recommendations
- Enable WordPress audit logging to capture plugin option updates and administrative actions
- Monitor for outbound clicks from admin sessions to unknown domains followed by immediate plugin activity
- Alert on modifications to plugin-managed database tables outside expected maintenance windows
How to Mitigate CVE-2025-47542
Immediate Actions Required
- Identify all WordPress sites running Simple Calendar for Elementor version 1.6.5 or earlier
- Deactivate the plugin until a patched version is available and applied
- Instruct administrators to log out of WordPress sessions before browsing untrusted sites
- Enforce least privilege so only necessary accounts hold administrator or editor roles
Patch Information
At the time of publication, the vendor advisory hosted on Patchstack lists all versions through 1.6.5 as affected. Site owners should upgrade to any subsequent release published by the vendor that addresses the CSRF flaw and confirm the fix version through the plugin changelog before deployment.
Workarounds
- Deactivate and remove the Simple Calendar for Elementor plugin if a patched version is not yet available
- Deploy a WordPress-aware WAF to block cross-origin state-changing requests to plugin endpoints
- Restrict WordPress admin access by IP allowlisting at the web server or firewall layer
- Require administrators to use isolated browser profiles when managing WordPress sites
