CVE-2025-3467: CWE-79 Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in langgenius langgenius/dify
An XSS vulnerability exists in langgenius/dify versions prior to 1.1.3, specifically affecting Firefox browsers. This vulnerability allows an attacker to obtain the administrator's token by sending a payload in the published chat. When the administrator views the conversation content through the monitoring/log function using Firefox, the XSS vulnerability is triggered, potentially exposing sensitive token information to the attacker.
AI Analysis
Technical Summary
CVE-2025-3467 is a high-severity Cross-Site Scripting (XSS) vulnerability classified under CWE-79, affecting the langgenius/dify product prior to version 1.1.3. This vulnerability specifically impacts Firefox browsers and arises from improper neutralization of input during web page generation. An attacker can exploit this flaw by injecting a malicious payload into the published chat feature. When an administrator subsequently views the conversation content through the monitoring or log function using Firefox, the embedded script executes, triggering the XSS vulnerability. This execution can lead to the exposure of sensitive information, notably the administrator's authentication token. The token compromise enables the attacker to potentially hijack the administrator session, leading to unauthorized access and control over the application. The vulnerability requires that the attacker can submit chat content and that the administrator uses Firefox to review logs, implying some user interaction and privileges are necessary. The CVSS v3.0 score of 8.0 reflects the high impact on confidentiality, integrity, and availability, with network attack vector, low attack complexity, and limited privileges required but user interaction needed. No known exploits are currently reported in the wild, and no patch links are provided yet, indicating that remediation may still be pending or in progress.
Potential Impact
For European organizations using langgenius/dify, this vulnerability poses a significant risk, especially for those relying on Firefox browsers for administrative monitoring. The exposure of administrator tokens can lead to full compromise of the affected system, allowing attackers to manipulate chat content, access sensitive data, or disrupt services. Given that chat and monitoring functions often contain critical operational or customer information, the breach could result in data leaks, reputational damage, and regulatory non-compliance under GDPR. The attack vector being network-based and requiring only limited privileges means that insiders or external attackers with minimal access could exploit this flaw. The impact on availability and integrity could disrupt business continuity, particularly for organizations using langgenius/dify in customer support or internal communications. The lack of known exploits in the wild provides a window for proactive mitigation, but the high severity score demands urgent attention.
Mitigation Recommendations
European organizations should immediately upgrade langgenius/dify to version 1.1.3 or later once available, as this version presumably addresses the vulnerability. Until a patch is applied, organizations should implement strict input validation and sanitization on chat inputs to prevent malicious script injection. Administrators should avoid using Firefox browsers for monitoring chat logs or switch to alternative browsers not affected by this vulnerability. Additionally, monitoring and logging of administrative sessions should be enhanced to detect unusual token usage or session anomalies. Employing Content Security Policy (CSP) headers can help mitigate the impact of XSS by restricting script execution. Network segmentation and limiting chat publishing permissions to trusted users can reduce the attack surface. Regular security awareness training should emphasize the risks of XSS and the importance of cautious handling of chat content. Finally, organizations should prepare incident response plans for potential token compromise scenarios.
