CVE-2024-12281 is a critical security vulnerability identified in the Homey theme for WordPress, developed by Fave Themes. This vulnerability arises from improper privilege management (CWE-269), where the theme's user registration process allows new users to assign themselves arbitrary roles, including privileged roles like Editor or Shop Manager. Since this flaw permits unauthenticated attackers to create accounts with elevated privileges, it effectively enables privilege escalation without requiring any authentication or user interaction. The vulnerability affects all versions up to and including 2.4.2 of the Homey theme. The CVSS v3.1 score of 9.8 indicates a critical severity, with an attack vector of network (AV:N), low attack complexity (AC:L), no privileges required (PR:N), no user interaction (UI:N), and impacts on confidentiality, integrity, and availability (C:H/I:H/A:H). Exploiting this vulnerability would allow attackers to modify site content, manage e-commerce operations, or potentially deploy malicious code, severely compromising the affected WordPress sites. Although no known exploits have been reported in the wild yet, the ease of exploitation and high impact make this a significant threat. The vulnerability remains unpatched as no patch links are provided, emphasizing the urgency for users to apply any forthcoming updates or implement workarounds.

The impact of CVE-2024-12281 is severe for organizations using the Homey WordPress theme, especially those running e-commerce sites or content-heavy platforms. Attackers exploiting this vulnerability can gain elevated privileges without authentication, allowing them to alter website content, manipulate product listings, access sensitive customer data, and potentially install backdoors or malware. This can lead to data breaches, loss of customer trust, financial losses, and reputational damage. The availability of the site can also be compromised if attackers delete or disrupt critical content or functionality. Given WordPress's widespread use globally, the vulnerability poses a broad risk, particularly to small and medium-sized businesses that may rely on the Homey theme for their online presence and may lack advanced security monitoring. The lack of required user interaction and low complexity of exploitation further increase the likelihood of attacks, potentially leading to widespread compromise if not addressed promptly.

1. Immediate action should be to update the Homey theme to a patched version once released by Fave Themes. Monitor official channels for patch announcements. 2. Until a patch is available, disable user self-registration or restrict registration to trusted users only via WordPress settings or plugins. 3. Implement role assignment validation by customizing the registration process to enforce default low-privilege roles (e.g., Subscriber) regardless of user input. 4. Employ Web Application Firewalls (WAFs) with custom rules to detect and block suspicious registration attempts that specify elevated roles. 5. Conduct regular audits of user accounts and roles to identify and remove any unauthorized privileged accounts. 6. Enhance monitoring and alerting for unusual account creation or privilege changes. 7. Educate site administrators on the risks and encourage immediate response to suspicious activity. 8. Consider isolating critical WordPress instances or using multi-factor authentication for administrative access to limit damage if compromise occurs.
