CVE-2025-58796 is a Stored Cross-Site Scripting (XSS) vulnerability classified under CWE-79, affecting the dudaster Elementor Element Condition plugin up to version 1.0.5. This vulnerability arises from improper neutralization of input during web page generation, allowing malicious scripts to be injected and stored within the application. When a victim user accesses the affected page, the malicious script executes in their browser context, potentially leading to session hijacking, credential theft, or unauthorized actions performed on behalf of the user. The vulnerability requires low privileges (PR:L) but does require user interaction (UI:R) to trigger the exploit. The attack vector is network-based (AV:N), meaning exploitation can occur remotely without physical access. The CVSS v3.1 base score is 6.5, indicating a medium severity level with a scope change (S:C), meaning the vulnerability affects components beyond the initially vulnerable component, impacting confidentiality, integrity, and availability to a limited extent (C:L/I:L/A:L). No known exploits are currently reported in the wild, and no patches have been linked yet. The vulnerability is particularly relevant for websites using the Elementor page builder plugin with the dudaster Element Condition add-on, which is popular among WordPress users for dynamic content display based on conditions. The lack of input sanitization or output encoding in this plugin allows attackers to inject persistent malicious scripts into pages, which can then affect any user visiting those pages.

For European organizations, this vulnerability poses a significant risk especially for businesses relying on WordPress-based websites that utilize the Elementor plugin ecosystem. Stored XSS can lead to compromise of user accounts, leakage of sensitive data, and defacement or manipulation of website content. This can damage brand reputation, lead to regulatory non-compliance (e.g., GDPR breaches if personal data is exposed), and result in financial losses due to fraud or remediation costs. E-commerce sites, government portals, and media outlets using this plugin are particularly at risk. The medium severity score reflects that while the vulnerability requires some user interaction and privileges, the potential for cross-site scripting to escalate into broader attacks (such as session hijacking or delivering malware) is notable. The scope change indicates that the impact can extend beyond the plugin itself, affecting the entire website and its users. Given the widespread use of WordPress in Europe and the popularity of Elementor, the threat is relevant across multiple sectors including public administration, retail, and services.

European organizations should immediately audit their WordPress installations to identify the presence of the dudaster Elementor Element Condition plugin, especially versions up to 1.0.5. Until an official patch is released, organizations should consider disabling or removing the plugin to eliminate the attack vector. Implementing Web Application Firewalls (WAFs) with rules to detect and block common XSS payloads can provide temporary protection. Additionally, organizations should enforce strict Content Security Policies (CSP) to restrict the execution of unauthorized scripts. Regular security scanning and penetration testing focused on XSS vulnerabilities should be conducted. User input validation and output encoding best practices must be reviewed and enforced in custom code. Monitoring logs for unusual activity or injection attempts can help detect exploitation attempts early. Finally, organizations should subscribe to vendor advisories for timely patch releases and apply updates promptly once available.
