CVE-2025-58786 is a Cross-site Scripting (XSS) vulnerability classified under CWE-79, specifically a DOM-Based XSS, found in the VW THEMES Ibtana – Ecommerce Product Addons plugin. This vulnerability arises from improper neutralization of input during web page generation, allowing malicious scripts to be injected and executed in the context of a victim's browser. The affected product versions include all versions up to 0.4.7.4. The vulnerability has a CVSS 3.1 base score of 6.5, indicating a medium severity level. The vector string (CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:L) shows that the attack can be performed remotely over the network with low attack complexity, requires privileges (PR:L) and user interaction (UI:R), and impacts confidentiality, integrity, and availability to a limited extent. The scope is changed (S:C), meaning the vulnerability affects components beyond the initially vulnerable component. This DOM-Based XSS allows attackers to execute arbitrary JavaScript in the context of the victim's browser session, potentially leading to session hijacking, credential theft, or unauthorized actions on behalf of the user. Since this is a DOM-based issue, the attack payload is executed as a result of client-side script processing, making detection and mitigation more challenging. No known exploits are reported in the wild yet, and no official patches or updates have been linked at the time of publication. The vulnerability is particularly relevant for websites using the Ibtana Ecommerce Product Addons plugin, which is used to extend ecommerce functionality in WordPress sites built with VW THEMES. Attackers could exploit this vulnerability by tricking authenticated users into clicking crafted links or visiting malicious pages, leading to execution of malicious scripts within their browser context.

For European organizations, especially those operating ecommerce platforms using WordPress with VW THEMES and the Ibtana Ecommerce Product Addons plugin, this vulnerability poses a significant risk. Successful exploitation could lead to theft of user credentials, session tokens, or other sensitive information, undermining customer trust and potentially violating GDPR requirements regarding data protection. The integrity of ecommerce transactions could be compromised, leading to fraudulent orders or unauthorized access to user accounts. Additionally, availability could be impacted if attackers leverage the vulnerability to perform actions that disrupt normal site operations. The medium severity rating reflects that while exploitation requires some privileges and user interaction, the potential for cross-site contamination (scope change) increases the risk to multiple components or users. Given the ecommerce context, financial losses and reputational damage are key concerns. Furthermore, the lack of a patch at the time of disclosure means organizations must act proactively to mitigate risk. The vulnerability also increases the attack surface for phishing campaigns targeting European customers, potentially amplifying the impact across the region.

1. Immediate mitigation should include disabling or removing the Ibtana Ecommerce Product Addons plugin until an official patch is released. 2. Implement Content Security Policy (CSP) headers with strict script-src directives to restrict execution of unauthorized scripts, which can help mitigate DOM-based XSS attacks. 3. Employ input validation and output encoding on all user-controllable inputs, especially those reflected in the DOM, to prevent malicious script injection. 4. Use security plugins or web application firewalls (WAFs) that can detect and block XSS attack patterns targeting WordPress sites. 5. Educate users and administrators about the risks of clicking suspicious links or interacting with untrusted content, as user interaction is required for exploitation. 6. Monitor web server and application logs for unusual activity or signs of attempted exploitation. 7. Once available, promptly apply official patches or updates from VW THEMES to remediate the vulnerability. 8. Conduct security testing, including penetration testing focused on DOM-based XSS, to identify and remediate similar vulnerabilities in custom themes or plugins.
