Langgenius: >> Dify Security Vulnerabilities
In langgenius/dify-web version 1.6.0, the authentication mechanism reveals the existence of user accounts by returning different error messages for non-existent and existing accounts. Specifically, when a login or registration attempt is made with a non-existent username or email, the system responds with a message such as "account not found." Conversely, when the username or email exists but the password is incorrect, a different error message is returned. This discrepancy allows an attacker to enumerate valid user accounts by analyzing the error responses, potentially facilitating targeted social engineering, brute force, or credential stuffing attacks.

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.

Dify is an open-source LLM app development platform. In version 1.8.1, a broken access control vulnerability on the /console/api/apps/<APP_ID>chat-messages?conversation_id=<CONVERSATION_ID>&limit=10 endpoint allows users in the same workspace to read chat messages of other users. A regular user is able to read the query data and the filename of the admins and probably other users chats, if they know the conversation_id. This impacts the confidentiality of chats. This issue has been patched in version 1.9.0.

langgenius/dify versions 1.1.0 to 1.1.2 are vulnerable to unsanitized input in the code node, allowing execution of arbitrary code with full root permissions. The vulnerability arises from the ability to override global functions in JavaScript, such as parseInt, before sandbox security restrictions are imposed. This can lead to unauthorized access to secret keys, internal network servers, and lateral movement within dify.ai. The issue is resolved in version 1.1.3.

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 version 1.2.0, there is insufficient filtering of user input by web applications. Attackers can use website vulnerabilities to inject malicious script code into web pages. This may result in a cross-site scripting (XSS) attack when a user browses these web pages. At time of posting, there is no known patched version.

DIFY is an open-source LLM app development platform. Prior to version 1.3.0, a clickjacking vulnerability was found in the default setup of the DIFY application, allowing malicious actors to trick users into clicking on elements of the web page without their knowledge or consent. This can lead to unauthorized actions being performed, potentially compromising the security and privacy of users. This issue has been fixed in version 1.3.0.

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 are improperly granted permissions to edit APP names, descriptions and icons. This access control flaw allows non-admin users to modify app details, despite being restricted from viewing apps, which poses a security risk to the integrity of the application. This issue has been patched in version 0.6.12. 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 modify app details.

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.
