CVE-2025-6994 is a critical privilege escalation vulnerability affecting the Reveal Listing plugin by SmartDataSoft for WordPress, specifically in versions up to and including 3.3. The vulnerability arises from improper privilege management (CWE-269) where the plugin allows users registering new accounts to specify their own user role via the 'listing_user_role' field. This flaw enables unauthenticated attackers to create accounts with elevated privileges, including administrator roles, without any authentication or user interaction. The vulnerability has a CVSS v3.1 base score of 9.8, indicating a critical severity with network attack vector, no required privileges or user interaction, and full impact on confidentiality, integrity, and availability. Exploiting this vulnerability would allow attackers to fully compromise affected WordPress sites by gaining administrative access, enabling them to modify content, install malicious plugins, exfiltrate data, or disrupt services. Although no known exploits are currently reported in the wild, the ease of exploitation and high impact make this a significant threat to WordPress sites using the Reveal Listing plugin.

For European organizations, this vulnerability poses a severe risk, especially for those relying on WordPress sites with the Reveal Listing plugin for business operations, customer engagement, or e-commerce. An attacker exploiting this flaw could gain full administrative control over the website, leading to data breaches involving personal data protected under GDPR, defacement of websites, insertion of malware or ransomware, and disruption of online services. This could result in financial losses, reputational damage, regulatory penalties, and operational downtime. Organizations in sectors such as retail, hospitality, real estate, and any service industry using Reveal Listing for listings or user-generated content are particularly vulnerable. The critical nature of this vulnerability demands immediate attention to prevent exploitation that could compromise sensitive customer and business data.

European organizations should immediately audit their WordPress installations to identify the presence of the Reveal Listing plugin and verify the version in use. Since no patch links are currently available, organizations should consider the following specific mitigations: 1) Temporarily disable or uninstall the Reveal Listing plugin until a secure update is released. 2) Implement web application firewall (WAF) rules to block or monitor requests containing the 'listing_user_role' parameter during account registration. 3) Restrict user registration on affected sites or enforce manual approval workflows to prevent automated or unauthorized account creation. 4) Monitor logs for suspicious account creation activities, especially those assigning elevated roles. 5) Harden WordPress user role assignment policies by restricting role changes to trusted administrators only. 6) Stay alert for official patches or updates from SmartDataSoft and apply them promptly once available. 7) Conduct regular security assessments and penetration tests focusing on privilege escalation vectors. These targeted actions go beyond generic advice and address the specific exploitation vector of this vulnerability.
