CVE-2025-39459 is a high-severity vulnerability classified under CWE-266 (Incorrect Privilege Assignment) affecting the Contempo Themes Real Estate 7 product, specifically versions up to 3.5.2. This vulnerability allows an attacker to escalate privileges improperly due to incorrect assignment of user permissions within the theme's code. The vulnerability is remotely exploitable (AV:N), requires no authentication (PR:N), and no user interaction (UI:N), making it particularly dangerous. The impact includes potential unauthorized access to restricted functionalities or data, leading to confidentiality, integrity, and availability compromises. Since the vulnerability affects a WordPress theme commonly used for real estate websites, exploitation could allow attackers to manipulate website content, access sensitive client information, or deploy further malicious payloads. The CVSS 3.1 base score of 7.3 reflects a high severity, indicating a significant risk to affected systems. No known public exploits are currently reported, and no patches have been linked yet, which suggests organizations should prioritize monitoring and mitigation efforts proactively.

For European organizations, especially those operating real estate platforms or websites using the Contempo Themes Real Estate 7 theme, this vulnerability poses a substantial risk. Exploitation could lead to unauthorized data exposure, including personal client data protected under GDPR, resulting in regulatory penalties and reputational damage. Additionally, attackers could alter website content or functionality, disrupting business operations and eroding customer trust. Given the theme's role in managing property listings and client interactions, integrity and availability impacts could directly affect revenue streams. The lack of required authentication and user interaction means attackers can exploit this vulnerability remotely and automatically, increasing the likelihood of widespread compromise if not addressed promptly.

Organizations should immediately audit their WordPress installations to identify the use of Contempo Themes Real Estate 7, particularly versions up to 3.5.2. Until an official patch is released, administrators should consider temporarily disabling or replacing the vulnerable theme to prevent exploitation. Implementing strict access controls at the WordPress level, such as limiting administrative privileges and employing role-based access control, can reduce the attack surface. Monitoring web server logs for unusual activity and deploying web application firewalls (WAFs) with custom rules to detect and block privilege escalation attempts targeting this theme is recommended. Additionally, organizations should ensure all WordPress core and plugins are up to date, maintain regular backups, and prepare incident response plans specific to web application compromise scenarios. Engaging with the theme vendor for timely patch releases and subscribing to vulnerability disclosure channels will aid in rapid remediation.
