CVE-2025-32920 is a security vulnerability classified as CWE-79, indicating an Improper Neutralization of Input During Web Page Generation, commonly known as Cross-site Scripting (XSS). This vulnerability affects the TemplateInvaders TI WooCommerce Wishlist plugin, specifically versions up to and including 2.10.0. The flaw allows an attacker to inject malicious scripts that are stored persistently within the wishlist functionality of the WooCommerce plugin. When a victim user accesses the affected page, the malicious script executes in their browser context. The vulnerability requires low attack complexity and only low privileges (PR:L), with user interaction (UI:R) necessary to trigger the exploit. The scope is changed (S:C), meaning the vulnerability can affect resources beyond the initially vulnerable component. The CVSS 3.1 base score is 6.5, indicating a medium severity level. The impact includes potential confidentiality, integrity, and availability losses, such as theft of session cookies, user impersonation, or defacement of web content. No known exploits are currently reported in the wild, and no patches have been linked yet. The vulnerability is relevant to web applications using the TI WooCommerce Wishlist plugin, a popular e-commerce extension for WordPress sites, which is widely used to enhance user shopping experience by allowing customers to save products for later. Stored XSS vulnerabilities are particularly dangerous because the malicious payload persists on the server and can affect multiple users, increasing the attack surface and potential damage. The vulnerability arises from insufficient input sanitization or output encoding during web page generation, allowing attackers to embed executable scripts in wishlist data fields.

For European organizations, especially those operating e-commerce platforms using WordPress and the TI WooCommerce Wishlist plugin, this vulnerability poses a significant risk. Attackers exploiting this flaw could hijack user sessions, steal sensitive customer data, or perform actions on behalf of users, leading to reputational damage, regulatory penalties under GDPR for data breaches, and financial losses. The stored nature of the XSS means multiple users can be affected, amplifying the impact. Additionally, attackers could use this vulnerability as a foothold to escalate attacks within the organization’s network or to distribute malware to customers. Given the widespread adoption of WooCommerce in Europe, the threat could affect a broad range of small to medium-sized enterprises reliant on this plugin for their online sales. The medium severity rating suggests that while the vulnerability is serious, exploitation requires some user interaction and low privileges, which somewhat limits the immediacy of risk but does not eliminate it. Organizations must consider the potential for cross-site request forgery, phishing, or session hijacking attacks stemming from this vulnerability.

European organizations should prioritize the following mitigation steps: 1) Immediate assessment of the TI WooCommerce Wishlist plugin version in use and upgrade to a patched version once available. In the absence of an official patch, consider temporarily disabling the wishlist functionality to prevent exploitation. 2) Implement robust input validation and output encoding on all user-supplied data fields related to the wishlist, ensuring that scripts cannot be injected or executed. 3) Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts in browsers, mitigating the impact of potential XSS payloads. 4) Conduct regular security audits and penetration testing focused on web application vulnerabilities, including stored XSS. 5) Educate users and administrators about the risks of clicking on suspicious links or interacting with untrusted content within the e-commerce platform. 6) Monitor web server logs and application behavior for unusual activity indicative of exploitation attempts. 7) Utilize Web Application Firewalls (WAF) with rules tailored to detect and block XSS attack patterns targeting WooCommerce plugins. These measures, combined, will reduce the likelihood and impact of exploitation beyond generic patching advice.
