The vulnerability CVE-2025-14984 affects the Gutenverse Form plugin for WordPress, which is widely used for contact forms, booking, reservation, and subscription functionalities within the WordPress block editor environment. The root cause is the plugin's framework component adding SVG files to the allowed MIME types via the WordPress upload_mimes filter without applying any sanitization or validation of the SVG content. SVG files can contain embedded JavaScript, and because the plugin does not neutralize or sanitize this input, an authenticated attacker with Author-level or higher privileges can upload a crafted SVG file containing malicious JavaScript code. This malicious script executes whenever the SVG is rendered or viewed by other users, leading to stored cross-site scripting. The attack vector is network-based, with low complexity, requiring only authenticated access but no user interaction to trigger the payload. The scope is potentially broad because the vulnerability affects all plugin versions up to 2.3.2, and many WordPress sites use this plugin. The impact includes partial compromise of confidentiality and integrity through session hijacking, credential theft, or unauthorized actions performed in the context of the victim's browser session. No known exploits are currently reported in the wild, but the vulnerability is publicly disclosed and could be weaponized. The CVSS 3.1 score of 6.4 reflects medium severity, with a confidentiality and integrity impact but no availability impact. The vulnerability is classified under CWE-79, indicating improper neutralization of input during web page generation.

For European organizations, this vulnerability can lead to significant risks including unauthorized access to user accounts, theft of sensitive data, and potential lateral movement within the affected WordPress environment. Organizations relying on Gutenverse Form for customer interactions, bookings, or subscriptions may face reputational damage and regulatory consequences if customer data is compromised. The stored XSS can be exploited to perform actions on behalf of legitimate users, potentially leading to privilege escalation or further exploitation of internal systems. Given the widespread use of WordPress in Europe, especially among SMEs and digital service providers, the attack surface is considerable. Additionally, GDPR implications arise if personal data is exposed or manipulated through such attacks. The requirement for authenticated access limits the threat to insiders or compromised accounts, but many WordPress sites allow multiple authors or contributors, increasing the risk. The lack of user interaction needed to trigger the exploit means that once the malicious SVG is uploaded, any user viewing the content is at risk. This can facilitate phishing, malware distribution, or session hijacking campaigns targeting European users.

European organizations should immediately audit their WordPress installations to identify the use of the Gutenverse Form plugin and verify the version in use. If running versions up to 2.3.2, they should restrict SVG uploads by disabling this file type unless absolutely necessary. Where SVG uploads are required, implement robust SVG sanitization using libraries such as SVG Sanitizer or similar tools that remove scripts and dangerous elements from SVG files before upload. Limit upload permissions strictly to trusted users with administrator roles rather than authors or contributors. Employ web application firewalls (WAFs) with rules to detect and block malicious SVG payloads or suspicious script execution patterns. Monitor logs for unusual upload activity or script execution errors. Educate content authors about the risks of uploading untrusted files. Regularly update the plugin once a patched version is released. Additionally, implement Content Security Policy (CSP) headers to restrict script execution sources, mitigating the impact of XSS attacks. Conduct periodic security assessments and penetration tests focusing on file upload functionalities.
