CVE-2025-46469 is a Stored Cross-Site Scripting (XSS) vulnerability identified in the Benjamin Buddle 'Send From' product, affecting versions up to 2.2. The vulnerability arises due to improper neutralization of input during web page generation, classified under CWE-79. Specifically, the application fails to adequately sanitize or encode user-supplied input before rendering it in web pages, allowing an attacker to inject malicious scripts that are persistently stored and subsequently executed in the browsers of users who access the affected pages. Stored XSS is particularly dangerous because the malicious payload is saved on the server side and delivered to multiple users, increasing the attack surface. Exploitation does not require authentication or user interaction beyond visiting a compromised page, making it easier for attackers to leverage this vulnerability for a range of malicious activities such as session hijacking, credential theft, defacement, or distribution of malware. The vulnerability was publicly disclosed on April 24, 2025, with no known exploits currently observed in the wild. No official patch or fix has been released at the time of this analysis, which increases the urgency for organizations using this product to apply mitigations or monitor for updates. The vulnerability affects the 'Send From' product, which is typically used for email sending or related communication functionalities, potentially exposing sensitive communication channels to compromise.

For European organizations, the impact of this Stored XSS vulnerability can be significant, particularly for entities relying on the 'Send From' product for internal or external communications. Exploitation could lead to unauthorized access to user sessions, theft of sensitive information such as credentials or personal data, and potential spread of malware through trusted communication channels. This can undermine confidentiality and integrity of communications, disrupt business operations, and damage organizational reputation. Sectors such as finance, healthcare, government, and critical infrastructure, which handle sensitive data and are frequent targets of cyberattacks, may face elevated risks. Additionally, compliance with European data protection regulations like GDPR could be jeopardized if personal data is exposed or mishandled due to this vulnerability. The lack of a patch increases the window of exposure, and attackers could exploit this vulnerability to establish persistent footholds or conduct targeted phishing campaigns leveraging the compromised platform.

Implement strict input validation and output encoding on all user-supplied data within the 'Send From' application to prevent injection of malicious scripts. Deploy Web Application Firewalls (WAFs) with custom rules to detect and block typical XSS payloads targeting the 'Send From' product until an official patch is available. Conduct regular security audits and code reviews focusing on input handling and sanitization mechanisms within the application. Restrict user privileges to minimize the ability of attackers to inject malicious content, applying the principle of least privilege. Monitor application logs and network traffic for unusual patterns indicative of XSS exploitation attempts. Educate users about the risks of clicking on suspicious links or interacting with unexpected content within the application. Stay informed on vendor communications for patches or updates and prioritize timely application of fixes once released. Consider isolating or segmenting the 'Send From' application environment to limit lateral movement in case of compromise.
