CVE-2025-58254 is a stored Cross-site Scripting (XSS) vulnerability classified under CWE-79, affecting the dtbaker StylePress plugin for Elementor, a popular WordPress page builder. This vulnerability arises from improper neutralization of input during web page generation, allowing malicious actors to inject and store arbitrary JavaScript code within the plugin's data fields. When a victim loads a page containing the injected payload, the malicious script executes in the context of the victim's browser, potentially leading to session hijacking, credential theft, defacement, or further exploitation of the victim's environment. The affected versions include all releases up to and including version 1.2.1. The vulnerability has a CVSS v3.1 base score of 6.5, indicating a medium severity level. The vector string (AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:L) reveals that the attack can be performed remotely over the network with low attack complexity, requires low privileges (authenticated user), and user interaction (victim must load the malicious page). The scope is changed, meaning the vulnerability affects resources beyond the initially vulnerable component. The impact includes low confidentiality, integrity, and availability impacts, but the stored nature of the XSS increases its risk profile compared to reflected XSS. No known exploits are currently reported in the wild, and no patches have been linked yet. This vulnerability is significant because Elementor and its extensions are widely used in WordPress sites, making the attack surface large and diverse.

For European organizations, this vulnerability poses a tangible risk especially to those relying on WordPress sites enhanced with Elementor and the StylePress plugin. Stored XSS can lead to session hijacking, enabling attackers to impersonate legitimate users, including administrators, potentially leading to unauthorized access and data breaches. This can compromise personal data protected under GDPR, resulting in regulatory fines and reputational damage. Additionally, attackers could use the vulnerability to deliver malware or redirect users to malicious sites, impacting customer trust and business continuity. The medium CVSS score suggests moderate risk, but the widespread use of WordPress in Europe, including government, education, and commercial sectors, amplifies the potential impact. The requirement for low privileges means that even users with minimal access can exploit this flaw, increasing the threat surface. The changed scope indicates that the vulnerability could affect other components or data beyond the plugin itself, potentially escalating the damage.

1. Immediate mitigation involves updating the StylePress for Elementor plugin to a patched version once available. Since no patch links are currently provided, organizations should monitor vendor advisories closely. 2. Implement Web Application Firewall (WAF) rules to detect and block malicious input patterns associated with XSS attacks targeting the plugin's input fields. 3. Enforce strict Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts in browsers, limiting the impact of any injected scripts. 4. Conduct thorough input validation and sanitization on all user-supplied data within the WordPress environment, especially for authenticated users who can submit content. 5. Limit user privileges to the minimum necessary, reducing the number of users who can inject content that might exploit this vulnerability. 6. Regularly audit and monitor logs for unusual activities or injection attempts related to the plugin. 7. Educate site administrators and users about the risks of clicking on suspicious links or loading untrusted content that could trigger stored XSS payloads. 8. Consider isolating or disabling the StylePress plugin temporarily if immediate patching is not feasible and the risk is deemed high.
