CVE-2025-49130 is a Cross-Site Scripting (XSS) vulnerability identified in the barryvdh laravel-translation-manager package, a tool used to manage Laravel translation files. The vulnerability exists in versions prior to 0.6.8 due to improper neutralization of user input during web page generation, classified under CWE-79. Specifically, the package fails to correctly validate and sanitize user-supplied data before rendering it in the web interface. This flaw allows an authenticated user with access to the translation manager to inject arbitrary HTML or JavaScript code into the application’s pages. When other users load these pages, the malicious scripts execute in their browsers, potentially enabling attackers to steal sensitive information such as session cookies, perform actions on behalf of the victim, or conduct other malicious activities like defacement or phishing. The vulnerability requires authentication and user interaction, limiting its exploitation scope to users with legitimate access to the translation manager interface. The issue has been addressed in version 0.6.8 of the package. The CVSS 4.0 score is 6.0 (medium severity), reflecting the network attack vector, low attack complexity, no privileges required beyond authenticated access, and user interaction needed. No known exploits are currently reported in the wild.

For European organizations using Laravel frameworks with the barryvdh laravel-translation-manager package, this vulnerability poses a moderate security risk. Since exploitation requires authenticated access, the threat primarily targets internal users or attackers who have compromised credentials. Successful exploitation can lead to session hijacking, unauthorized actions within the translation management interface, and potential lateral movement within the application environment. This can result in data leakage, unauthorized modification of translation files, or further compromise of web application components. Given the widespread use of Laravel in European SMEs and enterprises, especially in sectors like e-commerce, public administration, and software development, the vulnerability could impact confidentiality and integrity of internal translation management processes. However, the requirement for authentication and user interaction reduces the likelihood of large-scale automated exploitation. Organizations with strict access controls and monitoring may mitigate risk, but those with weaker internal controls or shared credentials face higher exposure.

To mitigate this vulnerability, European organizations should immediately upgrade the barryvdh laravel-translation-manager package to version 0.6.8 or later, where the input validation and sanitization issues have been fixed. Additionally, organizations should enforce strict access controls to limit translation manager access only to trusted and necessary personnel. Implement multi-factor authentication (MFA) for all users with access to the translation manager to reduce the risk of credential compromise. Conduct regular audits of user activity within the translation manager to detect suspicious behavior indicative of exploitation attempts. Employ web application firewalls (WAFs) configured to detect and block common XSS payloads targeting the translation manager interface. Developers should review customizations or integrations with the translation manager to ensure no additional unsanitized inputs are introduced. Finally, educate users with access about the risks of XSS and encourage cautious behavior when interacting with translation files or user-generated content.
