CVE-2025-49957 is a reflected Cross-Site Scripting (XSS) vulnerability identified in the 'Email Attachment by Order Status & Products' plugin developed by Weboccult Technologies Pvt Ltd, affecting versions up to and including 1.0.1. The vulnerability arises due to improper neutralization of user-supplied input during the generation of web pages, allowing attackers to inject malicious JavaScript code that is reflected back to users. When a victim interacts with a crafted URL containing the malicious payload, the injected script executes in the victim's browser context, potentially leading to session hijacking, credential theft, or unauthorized actions performed on behalf of the user. The CVSS 3.1 base score of 7.1 reflects a high severity, with attack vector being network (remote), low attack complexity, no privileges required, but user interaction necessary. The scope is changed, indicating that the vulnerability can affect components beyond the initially vulnerable plugin, impacting confidentiality, integrity, and availability to a limited extent. No patches or known exploits are currently reported, but the vulnerability is publicly disclosed and should be addressed promptly. The plugin is typically used in e-commerce environments to manage email attachments linked to order statuses and products, making it a target for attackers seeking to exploit customer-facing interfaces.

For European organizations, this vulnerability poses a significant risk, particularly for businesses relying on the affected plugin for order management and customer communications. Successful exploitation can lead to theft of sensitive customer data, session tokens, or credentials, enabling further compromise of user accounts and internal systems. It can also facilitate phishing attacks by injecting malicious content into legitimate web pages, damaging brand reputation and customer trust. The reflected XSS nature means that attackers must lure users into clicking malicious links, which can be distributed via email or other communication channels. Disruption of availability is possible if attackers use the vulnerability to execute scripts that crash or degrade service. Given the widespread use of e-commerce platforms in Europe, the impact could be substantial, especially for SMEs that may lack robust security monitoring. Compliance with GDPR also raises the stakes, as data breaches involving personal data can lead to regulatory penalties.

Organizations should immediately verify if they use the 'Email Attachment by Order Status & Products' plugin version 1.0.1 or earlier and plan for an upgrade once a patch is available. In the interim, implement strict input validation and output encoding on all user-supplied data to neutralize malicious scripts. Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts in browsers. Educate users and staff about the risks of clicking on suspicious links, especially those received via email. Monitor web server logs and application behavior for unusual requests that may indicate exploitation attempts. If feasible, deploy Web Application Firewalls (WAFs) with rules targeting reflected XSS patterns specific to this plugin. Conduct regular security assessments and penetration testing focused on web application vulnerabilities. Finally, maintain an incident response plan to quickly address any exploitation events.
