CVE-2025-58786 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 specific vulnerability affects the VW THEMES product 'Ibtana – Ecommerce Product Addons' up to version 0.4.7.4. The vulnerability is DOM-based XSS, meaning that the malicious script is executed as a result of modifying the DOM environment in the victim's browser, rather than being directly injected into the HTML response from the server. The CVSS v3.1 score is 6.5, reflecting a medium impact with vector metrics AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:L. This means the attack can be carried out remotely over the network with low attack complexity, requires low privileges and user interaction, and can affect confidentiality, integrity, and availability to a limited extent. The scope is changed (S:C), indicating that the vulnerability affects resources beyond the initially vulnerable component. Since this is a DOM-based XSS, an attacker could craft malicious URLs or input that, when processed by the vulnerable ecommerce addon, executes arbitrary JavaScript in the context of the victim's browser session. This could lead to session hijacking, defacement, or redirection to malicious sites, potentially compromising user data or the ecommerce platform's integrity. No patches or known exploits in the wild are currently reported, but the vulnerability is published and recognized by Patchstack and the CVE database.

For European organizations using VW THEMES Ibtana – Ecommerce Product Addons, this vulnerability poses a risk primarily to the confidentiality and integrity of user sessions and data. Ecommerce platforms are critical for business operations and customer trust; exploitation could lead to theft of user credentials, payment information, or unauthorized actions on behalf of users. The DOM-based nature means attacks could be delivered via phishing or malicious links, increasing the risk of targeted attacks on customers or employees. The vulnerability's scope change indicates potential for cross-component impact, possibly affecting other integrated modules or services. Given the ecommerce context, any compromise could result in financial losses, reputational damage, and regulatory consequences under GDPR if personal data is exposed. The requirement for low privileges and user interaction means attackers could exploit this vulnerability through social engineering, making it a practical threat. The absence of known exploits in the wild suggests a window for proactive mitigation before widespread abuse occurs.

1. Immediate review and update of the VW THEMES Ibtana – Ecommerce Product Addons to the latest version once a patch is released. Since no patch links are currently available, monitor vendor advisories closely. 2. Implement Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts and reduce the impact of XSS attacks. 3. Employ input validation and output encoding on all user-controllable inputs, especially those reflected in the DOM, to neutralize malicious scripts. 4. Conduct thorough security testing, including DOM-based XSS testing, on the ecommerce platform and any integrated addons. 5. Educate users and staff about phishing risks and the dangers of clicking on suspicious links to reduce the likelihood of successful exploitation. 6. Use web application firewalls (WAF) with rules tailored to detect and block XSS attack patterns targeting the ecommerce platform. 7. Monitor logs and user activity for unusual behavior that could indicate exploitation attempts. 8. Segregate ecommerce components and limit privileges to minimize the scope of impact if exploitation occurs.
