CVE-2025-49867 is a critical security vulnerability classified under CWE-266 (Incorrect Privilege Assignment) affecting the InspiryThemes RealHomes WordPress theme, specifically versions up to and including 4.4.0. This vulnerability allows an attacker to escalate privileges improperly due to flawed access control mechanisms within the theme's code. The vulnerability is remotely exploitable without requiring authentication or user interaction, as indicated by the CVSS vector (AV:N/AC:L/PR:N/UI:N). This means an unauthenticated attacker can exploit this flaw over the network with low complexity, gaining elevated privileges that should normally be restricted. The impact of such privilege escalation is severe, potentially allowing the attacker to gain administrative control over the affected WordPress site, leading to full confidentiality, integrity, and availability compromise. This could include unauthorized data access, modification or deletion of content, installation of backdoors or malware, and disruption of site operations. Although no known exploits are currently reported in the wild, the high CVSS score of 9.8 underscores the critical nature of this vulnerability and the urgency for patching or mitigation. The lack of available patches at the time of reporting increases the risk window for affected users. Given that RealHomes is a popular real estate theme used by many agencies and property listing websites, exploitation could have significant consequences for businesses relying on this platform.

For European organizations, especially real estate agencies, property management firms, and related service providers using the RealHomes theme, this vulnerability poses a critical risk. Exploitation could lead to unauthorized access to sensitive client data, including personal and financial information, damaging customer trust and violating data protection regulations such as the GDPR. The integrity of property listings and transactional data could be compromised, leading to misinformation or fraud. Availability impacts could disrupt business operations and online presence, causing financial losses and reputational damage. Additionally, compromised sites could be leveraged as part of broader attack campaigns, such as phishing or malware distribution, further amplifying the threat landscape in Europe. The critical severity and ease of exploitation make it imperative for European organizations to address this vulnerability promptly to maintain compliance and protect their digital assets.

Given the absence of an official patch at the time of this report, European organizations should implement immediate compensating controls. These include restricting network access to the WordPress administration interface via IP whitelisting or VPN access, thereby limiting exposure to potential attackers. Administrators should audit user roles and permissions within WordPress to ensure no unnecessary privileges are granted. Employing Web Application Firewalls (WAFs) with custom rules to detect and block suspicious requests targeting RealHomes theme endpoints can reduce exploitation risk. Regular monitoring of logs for unusual activity related to privilege escalation attempts is crucial. Organizations should also plan for rapid deployment of patches once available from InspiryThemes and maintain updated backups to enable swift recovery if compromise occurs. Finally, educating site administrators about this vulnerability and encouraging minimal use of third-party themes or plugins without verified security track records can reduce future risks.
