CVE-2025-64250 identifies an open redirect vulnerability in the wpWax Directorist WordPress plugin, affecting all versions up to and including 8.5.6. Open redirect vulnerabilities occur when an application accepts a user-controlled input that specifies a link to an external site and redirects users to that site without sufficient validation. In this case, Directorist improperly validates URLs used in redirection, allowing attackers to craft malicious URLs that appear legitimate but redirect victims to untrusted, potentially harmful websites. This can be exploited in phishing campaigns where attackers lure users into clicking seemingly trustworthy links that lead to credential harvesting or malware distribution sites. The vulnerability does not require authentication but does require user interaction (clicking the malicious link). The CVSS 3.1 score of 6.1 reflects a medium severity, with a vector indicating network attack vector, low attack complexity, no privileges required, user interaction needed, and a scope change. The impact affects confidentiality and integrity by enabling phishing and social engineering attacks, but does not affect availability. No known public exploits exist yet, and no patches have been linked, indicating that users should monitor for updates from wpWax. Directorist is a popular directory and listing plugin for WordPress, widely used by organizations to manage business listings, events, and directories, making this vulnerability relevant to many websites relying on this plugin for user engagement and information dissemination.

For European organizations, this vulnerability poses a significant risk primarily through phishing attacks that can compromise user credentials, lead to unauthorized access, or facilitate further social engineering exploits. Organizations using Directorist for customer-facing directories or listings may see their users redirected to malicious sites, damaging trust and potentially leading to data breaches. The confidentiality of user data is at risk if phishing leads to credential theft. Integrity is impacted as attackers can manipulate user navigation flows. Although availability is not directly affected, the reputational damage and potential regulatory consequences under GDPR for failing to protect user data can be substantial. The threat is particularly relevant for sectors with high user interaction such as e-commerce, local business directories, and event management platforms. The lack of known exploits in the wild currently reduces immediate risk but does not eliminate the potential for future attacks once exploit code becomes available.

European organizations should take proactive steps to mitigate this vulnerability. First, monitor wpWax and Directorist plugin updates closely and apply patches immediately once released. Until a patch is available, implement strict input validation and sanitization on URL parameters used for redirection within the plugin or via web application firewalls (WAFs) to block suspicious redirect attempts. Employ Content Security Policy (CSP) headers to restrict navigation to trusted domains. Educate users and staff about phishing risks and encourage verification of URLs before clicking. Use multi-factor authentication (MFA) to reduce the impact of credential theft. Conduct regular security audits of WordPress plugins and remove or replace plugins that are no longer maintained or have known vulnerabilities. Additionally, monitor logs for unusual redirect patterns and suspicious user activity that could indicate exploitation attempts.
