Dify is an LLM application development platform. In Dify versions through 1.9.1, the MCP OAuth component is vulnerable to cross-site scripting when a victim connects to an attacker-controlled remote MCP server. The vulnerability exists in the OAuth flow implementation where the authorization_url provided by a remote MCP server is directly passed to window.open without validation or sanitization. An attacker can craft a malicious MCP server that returns a JavaScript URI (such as javascript:alert(1)) in the authorization_url field, which is then executed when the victim attempts to connect to the MCP server. This allows the attacker to execute arbitrary JavaScript in the context of the Dify application.
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.
Dify is an open-source LLM app development platform. In versions 0.6.8 and prior, a vulnerability was identified in the DIFY AI where normal users are improperly granted permissions to export APP DSL. The feature in '/export' should only allow administrator users to export DSL. A workaround for this vulnerability involves updating the access control mechanisms to enforce stricter user role permissions and implementing role-based access controls (RBAC) to ensure that only users with admin privileges can export the APP DSL. This vulnerability is fixed in 0.6.13.
A Server-Side Request Forgery (SSRF) vulnerability was identified in langgenius/dify version 0.10.2. The vulnerability occurs in the 'Create Knowledge' section when uploading DOCX files. If an external relationship exists in the DOCX file, the reltype value is requested as a URL using the 'requests' module instead of the 'ssrf_proxy', leading to an SSRF vulnerability. This issue was fixed in version 0.11.0.
A stored cross-site scripting (XSS) vulnerability exists in langgenius/dify version latest, specifically in the chat log functionality. The vulnerability arises because certain HTML tags like <input> and <form> are not disallowed, allowing an attacker to inject malicious HTML into the log via prompts. When an admin views the log containing the malicious HTML, the attacker could steal the admin's credentials or sensitive information. This issue is fixed in version 0.12.1.
A vulnerability in langgenius/dify versions <=v0.9.1 allows for code injection via internal SSRF requests in the Dify sandbox service. This vulnerability enables an attacker to execute arbitrary Python code with root privileges within the sandbox environment, potentially leading to the deletion of the entire sandbox service and causing irreversible damage.
