CVE-2026-57641 Overview
CVE-2026-57641 is an unauthenticated Cross-Site Request Forgery (CSRF) vulnerability affecting the Real Estate 7 WordPress theme in versions up to and including 3.5.9. The flaw is classified under [CWE-352] and enables attackers to trigger state-changing actions on behalf of authenticated users without their consent. Exploitation requires user interaction, typically achieved by luring a logged-in user to visit an attacker-controlled page. Successful exploitation can disrupt the availability of the affected WordPress site.
Critical Impact
Attackers can abuse authenticated user sessions through forged requests, leading to high-impact availability disruption on WordPress sites running vulnerable versions of the Real Estate 7 theme.
Affected Products
- Real Estate 7 WordPress theme, versions <= 3.5.9
- WordPress installations bundling the vulnerable theme
- Sites relying on Real Estate 7 for property listing functionality

Technical Details for CVE-2026-57641
Vulnerability Analysis
The Real Estate 7 theme fails to enforce anti-CSRF protections on sensitive state-changing endpoints. Requests processed by the theme do not validate a nonce or verify request origin, allowing forged HTTP requests to succeed when a victim visits a malicious page. Because the flaw is exploitable pre-authentication from the attacker perspective, no attacker credentials are required. The theme accepts the browser-supplied cookies of the victim and executes the requested action in their context.
Root Cause
The root cause is missing or improper Cross-Site Request Forgery protections on theme actions. WordPress provides wp_nonce_field() and check_admin_referer() primitives designed to prevent this class of issue, but the affected code paths in Real Estate 7 do not invoke them. This omission maps directly to [CWE-352]: Cross-Site Request Forgery.
Attack Vector
Exploitation occurs over the network and requires user interaction. An attacker crafts an HTML page or email containing a hidden form or image tag that issues a request to the target WordPress site. When a signed-in user loads the attacker's content, the browser transmits the user's session cookies alongside the forged request. The vulnerable theme processes the request as legitimate, producing an availability-impacting outcome on the affected site. Refer to the Patchstack WordPress Vulnerability advisory for further technical details.
Detection Methods for CVE-2026-57641
Indicators of Compromise
- Unexpected POST requests to Real Estate 7 theme endpoints originating from external Referer headers
- WordPress audit log entries showing state changes without corresponding admin session activity
- Anomalous configuration or content changes tied to accounts that did not initiate them
Detection Strategies
- Inspect web server access logs for cross-origin Referer values targeting Real Estate 7 theme paths
- Deploy WordPress security plugins that flag requests lacking valid nonces on privileged actions
- Correlate browser-driven state changes with authenticated session timelines to identify forged submissions
Monitoring Recommendations
- Enable verbose audit logging for administrative and editor accounts on WordPress
- Monitor outbound links in comments, emails, and third-party content that could serve CSRF payloads
- Alert on HTTP requests to sensitive theme endpoints missing X-WP-Nonce or referrer validation
How to Mitigate CVE-2026-57641
Immediate Actions Required
- Identify all WordPress installations running the Real Estate 7 theme at version 3.5.9 or earlier
- Restrict administrative sessions to dedicated browsers or profiles to reduce CSRF exposure
- Apply the vendor's patched theme release as soon as it becomes available via the WordPress dashboard
Patch Information
At the time of publication, refer to the Patchstack WordPress Vulnerability advisory for the current fixed version and vendor guidance. Update the Real Estate 7 theme to a release that adds nonce verification and referrer checks on state-changing endpoints.
Workarounds
- Deploy a web application firewall rule requiring same-origin Referer or Origin headers on theme POST endpoints
- Enforce SameSite=Strict or SameSite=Lax attributes on WordPress authentication cookies
- Instruct administrators to log out of WordPress when browsing untrusted sites to limit session abuse
