CVE-2025-54052 is a high-severity vulnerability classified as CWE-352, indicating a Cross-Site Request Forgery (CSRF) weakness in the Realtyna Organic IDX plugin, a WordPress plugin used for real estate listings integration. The vulnerability allows an attacker to perform unauthorized actions on behalf of an authenticated user by exploiting the lack of proper CSRF protections. Specifically, this CSRF flaw enables PHP Local File Inclusion (LFI), which can lead to severe consequences such as arbitrary file inclusion and execution within the context of the vulnerable web application. The affected versions include all versions up to 5.0.0, with no specific lower bound version identified. The CVSS 3.1 base score is 7.5, reflecting a high impact on confidentiality, integrity, and availability, with an attack vector of network (remote), requiring no privileges but some user interaction. The attack complexity is high, indicating that exploitation requires specific conditions or crafted requests. The vulnerability could allow attackers to include local files on the server, potentially exposing sensitive information or enabling remote code execution if combined with other vulnerabilities. No known exploits are currently reported in the wild, and no patches have been linked yet, suggesting that remediation may still be pending or in development. The vulnerability affects the Realtyna Organic IDX plugin, which is used primarily in real estate websites to display property listings, making it a critical concern for organizations relying on this plugin for their online presence.

For European organizations, especially those in the real estate sector or those operating websites with real estate listings using the Realtyna Organic IDX plugin, this vulnerability poses a significant risk. Exploitation could lead to unauthorized actions performed on behalf of legitimate users, including administrators, potentially resulting in data leakage, website defacement, or further compromise through local file inclusion. The confidentiality of sensitive client data, such as property details and user information, could be jeopardized. Integrity of website content and availability of services may also be disrupted, damaging business reputation and causing operational downtime. Given the plugin's integration with WordPress, a widely used CMS in Europe, the attack surface is broad. Additionally, the high severity and the possibility of chaining this vulnerability with others could lead to full system compromise. Organizations handling personal data under GDPR must be particularly cautious, as breaches could lead to regulatory penalties and loss of customer trust.

Organizations should immediately audit their use of the Realtyna Organic IDX plugin and identify if they are running affected versions (up to 5.0.0). Until an official patch is released, mitigation steps include: 1) Implementing Web Application Firewall (WAF) rules to detect and block suspicious CSRF attempts and local file inclusion patterns targeting the plugin endpoints. 2) Enforcing strict Content Security Policy (CSP) headers to limit the impact of injected content. 3) Restricting access to the plugin's administrative interfaces via IP whitelisting or VPN access to reduce exposure. 4) Monitoring web server logs for unusual requests indicative of CSRF or LFI exploitation attempts. 5) Encouraging users to log out of administrative sessions when not in use to minimize the window of opportunity for CSRF attacks. 6) Applying the principle of least privilege to WordPress user roles to limit the damage potential of compromised accounts. 7) Preparing for patch deployment by subscribing to vendor advisories and testing updates in staging environments before production rollout. These targeted measures go beyond generic advice by focusing on the specific attack vectors and plugin behavior.
