CVE-2025-47505 is a security vulnerability classified as CWE-79, which corresponds to Improper Neutralization of Input During Web Page Generation, commonly known as Cross-site Scripting (XSS). This specific vulnerability affects the 'Product Time Countdown for WooCommerce' plugin developed by ProWCPlugins, versions up to and including 1.6.2. The vulnerability is a Stored XSS, meaning that malicious input submitted by an attacker is stored persistently by the application and later rendered in web pages viewed by other users without proper sanitization or encoding. This flaw allows an attacker with at least low privileges (PR:L) and requiring user interaction (UI:R) to inject malicious scripts into the web interface. The CVSS v3.1 base score is 6.5, indicating a medium severity level. The vector indicates that the attack can be performed remotely over the network (AV:N) with low attack complexity (AC:L), but requires some privileges and user interaction. The vulnerability impacts confidentiality, integrity, and availability (C:L/I:L/A:L) of the affected system, and the scope is changed (S:C), meaning the vulnerability affects resources beyond the security scope of the vulnerable component. No known exploits are currently reported in the wild, and no patches have been linked yet. The vulnerability was published on May 7, 2025, and has been enriched by CISA, indicating recognition by US cybersecurity authorities. Stored XSS in e-commerce plugins like WooCommerce can lead to session hijacking, credential theft, defacement, or redirection to malicious sites, potentially impacting both administrators and customers interacting with the affected plugin's countdown timers or related UI elements.

For European organizations using WooCommerce with the affected 'Product Time Countdown' plugin, this vulnerability poses a significant risk. Attackers could exploit the Stored XSS to execute arbitrary JavaScript in the context of users' browsers, potentially stealing session cookies, performing unauthorized actions, or delivering malware. This can lead to data breaches involving customer personal data, payment information, and order details, violating GDPR requirements and resulting in regulatory penalties. The integrity of the e-commerce platform could be compromised, damaging brand reputation and customer trust. Availability impacts could arise if attackers use the vulnerability to inject scripts that disrupt normal site operations or launch further attacks. Given the widespread use of WooCommerce across European small and medium enterprises (SMEs) and larger retailers, the risk extends across multiple sectors including retail, hospitality, and services. The requirement for low privileges and user interaction means that attackers might leverage social engineering or compromised accounts to trigger the exploit, increasing the attack surface. The scope change indicates that the vulnerability could affect components beyond the plugin itself, potentially impacting the entire website or connected systems.

European organizations should immediately audit their WooCommerce installations to identify if the 'Product Time Countdown for WooCommerce' plugin version 1.6.2 or earlier is in use. Until an official patch is released, administrators should consider disabling or removing the vulnerable plugin to eliminate the attack vector. Implementing Web Application Firewall (WAF) rules that detect and block typical XSS payloads targeting the plugin's input fields can provide temporary protection. Additionally, enforcing Content Security Policy (CSP) headers can help mitigate the impact of injected scripts by restricting script execution sources. Organizations should review user roles and permissions to minimize the number of users with privileges that could be leveraged to inject malicious input. Regularly monitoring logs for suspicious activities related to the plugin and user input fields is recommended. Once a patch becomes available, prompt application of updates is critical. Furthermore, educating staff about phishing and social engineering risks can reduce the likelihood of attackers gaining the necessary user interaction to exploit the vulnerability.
