Langgenius: >> Dify >> 0.3.20 Security Vulnerabilities
Dify before version 1.14.0 contains an authorization bypass vulnerability that allows authenticated users to read the full contents of files uploaded by other users within the same tenant by supplying an arbitrary file UUID in the files array of a chat-messages request. Attackers can exploit insufficient permission verification in the chat-messages endpoints to access files without ownership validation, bypassing workspace separation and signed URL protections to retrieve sensitive file contents through workflow processing.

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. Prior to version 0.6.12, a normal user is able to access and modify APP orchestration, even though the web UI of APP orchestration is not presented for a normal user. This access control flaw allows non-admin users to make unauthorized access and changes on the APPSs. This issue has been patched in version 0.6.12. A workaround for this vulnerability involves updating the 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 access Orchestration of the APPs.

Dify is an open-source LLM app development platform. Prior to version 0.6.12, a vulnerability was identified in the DIFY where normal users can enable or disable apps through the API, even though the web UI button for this action is disabled and normal users are not permitted to make such changes. This access control flaw allows non-admin users to make unauthorized changes, which can disrupt the functionality and availability of the APPS. This issue has been patched in version 0.6.12. A workaround for this vulnerability involves updating the API 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 send enable or disable requests for apps.

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.
