CVE-2025-62058 is a cross-site scripting (XSS) vulnerability identified in the Houzez Theme - Functionality plugin developed by favethemes, which is widely used in WordPress websites focused on real estate and property listings. The vulnerability stems from improper neutralization of user-supplied input during the generation of web pages, allowing malicious scripts to be injected and executed in the context of the victim's browser. This flaw affects all versions prior to 4.2.0 of the plugin. The CVSS 3.1 base score of 6.5 indicates a medium severity, with an attack vector of network (remote exploitation), low attack complexity, requiring low privileges but user interaction, and a scope change indicating that exploitation can affect components beyond the vulnerable plugin. The impact includes partial loss of confidentiality, integrity, and availability, as attackers can execute arbitrary scripts that may steal session tokens, manipulate page content, or perform actions on behalf of authenticated users. Although no known exploits are currently reported in the wild, the vulnerability presents a credible risk to websites using this theme, especially those handling sensitive user data or financial transactions. The vulnerability was reserved and published in October 2025, with no patch links currently available, suggesting that a fix is forthcoming or pending deployment. Given the plugin’s niche in real estate, targeted attacks could aim at defacing listings, stealing user credentials, or redirecting users to malicious sites.

For European organizations, particularly those operating real estate platforms or property listing websites using WordPress with the Houzez Theme - Functionality plugin, this vulnerability can lead to significant reputational damage and data breaches. Attackers exploiting this XSS flaw could hijack user sessions, steal personal information, or inject malicious content that compromises end-user trust. The partial compromise of confidentiality and integrity could expose client data or allow unauthorized changes to listings and transactions. Availability impacts, while less severe, could disrupt website functionality through script-based attacks. Given the widespread adoption of WordPress in Europe and the importance of digital real estate services, affected organizations may face regulatory scrutiny under GDPR if personal data is compromised. Additionally, the requirement for user interaction means phishing or social engineering could be leveraged to increase exploitation success, raising the risk profile for organizations with large user bases.

Organizations should immediately inventory their WordPress installations to identify the use of the Houzez Theme - Functionality plugin and verify the version in use. Until a patch is released, applying temporary mitigations such as disabling or restricting plugin functionality that processes user input can reduce exposure. Implementing robust input validation and output encoding on all user-supplied data within the theme’s codebase is critical. Deploying Content Security Policy (CSP) headers can help mitigate the impact of injected scripts by restricting the sources from which scripts can be loaded. Monitoring web server and application logs for unusual activity or script injection attempts is advised. User education to recognize phishing attempts that could trigger user interaction is also important. Once version 4.2.0 or later is available, organizations must promptly apply the update. Additionally, web application firewalls (WAFs) with XSS detection rules can provide an additional layer of defense during the interim period.
