CVE-2025-49957 is a reflected Cross-site Scripting (XSS) vulnerability identified in the Email Attachment by Order Status & Products plugin by Weboccult Technologies Pvt Ltd, affecting versions up to 1.0.1. The vulnerability stems from improper neutralization of user-supplied input during web page generation, which allows attackers to inject malicious JavaScript code into web pages viewed by other users. This reflected XSS occurs when an attacker crafts a specially designed URL containing malicious script code that is reflected back by the vulnerable web application without proper sanitization or encoding. When a victim clicks on the malicious link, the injected script executes in their browser context, potentially enabling attackers to steal session cookies, perform actions on behalf of the user, redirect users to phishing or malware sites, or manipulate page content. The vulnerability does not require authentication, increasing its risk profile, and does not depend on stored data, making it easier to exploit via social engineering. Although no public exploits are currently known, the vulnerability is published and could be targeted once exploit code becomes available. The affected plugin is typically used in e-commerce or order management environments to attach files based on order status and products, meaning that compromised systems could expose sensitive customer or order data. The lack of a CVSS score necessitates an assessment based on impact and exploitability factors. Given the reflected nature, ease of exploitation, and potential for significant confidentiality and integrity breaches, this vulnerability is assessed as high severity. No patches or mitigation links are currently provided, indicating that users must monitor vendor updates closely. Defenders should focus on input validation, output encoding, and deploying Content Security Policies to mitigate risk until patches are available.

For European organizations, this vulnerability could lead to unauthorized access to sensitive customer and order information, undermining confidentiality and data integrity. Attackers exploiting this XSS flaw could hijack user sessions, leading to unauthorized transactions or data manipulation, which is particularly critical for e-commerce platforms prevalent in Europe. The reflected XSS can also facilitate phishing attacks by redirecting users to malicious sites, increasing the risk of credential theft and malware infections. Organizations may suffer reputational damage and potential regulatory penalties under GDPR if customer data is compromised. The disruption caused by exploitation could affect availability indirectly by eroding user trust and causing operational interruptions. Since the plugin is used in order management workflows, any compromise could impact business continuity and customer satisfaction. The lack of known exploits currently reduces immediate risk but does not eliminate the threat, as attackers often develop exploits rapidly after disclosure. European organizations with significant online retail operations or those integrating this plugin into their systems should prioritize mitigation to prevent exploitation.

1. Monitor Weboccult Technologies Pvt Ltd communications and security advisories for official patches or updates addressing CVE-2025-49957 and apply them promptly. 2. Implement strict input validation on all user-supplied data, ensuring that inputs are sanitized to remove or encode potentially malicious characters before processing or rendering. 3. Apply context-appropriate output encoding (e.g., HTML entity encoding) when reflecting user input in web pages to prevent script execution. 4. Deploy Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts and reduce the impact of potential XSS attacks. 5. Educate users and staff about the risks of clicking on suspicious links, especially those received via email or external sources, to reduce social engineering attack vectors. 6. Conduct regular security assessments and penetration testing focusing on web application vulnerabilities, including XSS, to identify and remediate weaknesses proactively. 7. Where feasible, consider isolating or sandboxing the plugin’s functionality to limit the scope of potential exploitation. 8. Review and harden session management mechanisms to detect and prevent session hijacking attempts. 9. Maintain comprehensive logging and monitoring to detect unusual activities that may indicate exploitation attempts. 10. If immediate patching is not possible, consider temporarily disabling the vulnerable plugin or restricting its access to trusted users only.
