CVE-2025-47626 is a medium severity vulnerability classified as CWE-79, indicating an Improper Neutralization of Input During Web Page Generation, commonly known as Cross-site Scripting (XSS). This vulnerability affects the 'Submission DOM tracking for Contact Form 7' plugin developed by apasionados. The flaw allows for Stored XSS attacks, where malicious scripts injected by an attacker are permanently stored on the target system and executed when a user accesses the affected web page. Specifically, the vulnerability arises from insufficient sanitization or encoding of user-supplied input during the generation of web pages, enabling attackers to inject arbitrary JavaScript code. The affected versions include all versions up to 2.0, with no specific lower bound version identified. The CVSS v3.1 score is 5.9, reflecting a medium severity level, with the vector indicating network attack vector (AV:N), low attack complexity (AC:L), requiring high privileges (PR:H), user interaction (UI:R), scope changed (S:C), and low impact on confidentiality, integrity, and availability (C:L/I:L/A:L). No known exploits are currently reported in the wild, and no patches are linked yet. The vulnerability was published on May 7, 2025, and has been enriched by CISA, indicating recognition by US cybersecurity authorities. The plugin is an extension for Contact Form 7, a widely used WordPress plugin for creating contact forms, which means the vulnerability could affect many WordPress sites using this specific tracking extension. Stored XSS can lead to session hijacking, defacement, or redirection to malicious sites, impacting users and administrators interacting with the vulnerable forms.

For European organizations, the impact of CVE-2025-47626 can be significant, especially for those relying on WordPress websites with Contact Form 7 and the Submission DOM tracking plugin. Stored XSS vulnerabilities can compromise the confidentiality and integrity of user data by enabling attackers to steal session cookies, perform actions on behalf of authenticated users, or deliver malware. This can lead to reputational damage, regulatory non-compliance (e.g., GDPR violations due to data breaches), and potential financial losses. Since the vulnerability requires high privileges and user interaction, the risk is somewhat mitigated but still relevant for organizations with multiple administrators or users interacting with the forms. The scope change in the CVSS vector indicates that exploitation can affect resources beyond the vulnerable component, potentially impacting the entire web application or user base. Given the popularity of WordPress in Europe, especially among SMEs and public sector entities, exploitation could disrupt services, erode user trust, and expose sensitive information. Additionally, attackers could leverage this vulnerability as a foothold for further attacks within the network or to pivot to other systems.

To mitigate CVE-2025-47626, European organizations should: 1) Immediately audit their WordPress installations to identify the presence of the 'Submission DOM tracking for Contact Form 7' plugin and verify its version. 2) Disable or remove the plugin if it is not essential to reduce the attack surface. 3) Monitor for updates or patches from the vendor 'apasionados' and apply them promptly once available. 4) Implement Web Application Firewalls (WAFs) with rules to detect and block common XSS payloads targeting Contact Form 7 forms. 5) Enforce strict Content Security Policies (CSP) to restrict the execution of unauthorized scripts. 6) Conduct regular security training for administrators and users to recognize and avoid interacting with suspicious content. 7) Review and harden user privilege assignments to minimize high privilege accounts that can be exploited. 8) Employ security plugins that sanitize and validate all user inputs at the application level. 9) Perform regular security scans and penetration tests focusing on XSS vulnerabilities in web forms. These steps go beyond generic advice by focusing on plugin-specific actions, privilege management, and layered defenses tailored to the affected environment.
