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 1.0.1. The vulnerability stems from improper neutralization of input during web page generation, meaning that user-supplied data is not correctly sanitized or encoded before being included in the HTML output. This allows an attacker to craft a malicious URL or input that, when visited or submitted by a victim, causes the victim's browser to execute attacker-controlled JavaScript code. The attack vector is remote (network accessible), requires no privileges (no authentication), but does require user interaction (clicking a malicious link or submitting crafted input). The vulnerability has a CVSS v3.1 base score of 7.1, indicating high severity, with impact on confidentiality, integrity, and availability (C:L, I:L, A:L). Potential consequences include session hijacking, theft of sensitive information, defacement, or redirection to malicious sites. Although no known exploits are currently in the wild, the vulnerability's characteristics make it a viable target for attackers, especially in environments where the affected plugin is used to manage email attachments by order status and products, likely in e-commerce or order management contexts. The reflected XSS nature means the attack is transient and requires user interaction but can be leveraged in phishing campaigns or combined with other vulnerabilities for greater impact. The lack of available patches at the time of publication necessitates immediate mitigation efforts by affected organizations.

For European organizations, the impact of CVE-2025-49957 can be significant, particularly for those operating e-commerce platforms or using the affected Weboccult plugin to manage order-related email attachments. Exploitation could lead to unauthorized disclosure of sensitive customer data, session hijacking allowing attackers to impersonate legitimate users, and potential defacement or redirection attacks that damage brand reputation. The reflected XSS can also serve as a stepping stone for more complex attacks such as delivering malware or conducting phishing campaigns targeting employees or customers. Given the interconnected nature of European digital services and strict data protection regulations like GDPR, any data breach resulting from this vulnerability could lead to regulatory penalties and loss of customer trust. The requirement for user interaction means social engineering is a likely attack vector, increasing risk in organizations with less cybersecurity awareness. Additionally, the vulnerability could disrupt availability of order processing services, impacting business continuity and revenue. Organizations relying on this plugin without timely remediation face elevated risk of compromise.

To mitigate CVE-2025-49957, European organizations should implement the following specific measures: 1) Immediately identify and inventory all instances of the 'Email Attachment by Order Status & Products' plugin in use and verify version numbers. 2) Apply vendor patches as soon as they become available; if no patch exists, consider disabling or replacing the plugin temporarily. 3) Implement strict input validation and output encoding on all user-supplied data within the affected application to neutralize malicious scripts. 4) Deploy Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts in browsers. 5) Educate users and staff about the risks of clicking unsolicited or suspicious links, especially those related to order status or email attachments. 6) Monitor web server logs and application behavior for anomalous requests indicative of XSS exploitation attempts. 7) Use web application firewalls (WAFs) with rules designed to detect and block reflected XSS payloads targeting the affected plugin. 8) Conduct regular security assessments and penetration testing focusing on web input handling. These targeted actions go beyond generic advice by focusing on the specific plugin and attack vectors involved.
