A vulnerability in langgenius/dify v0.10.1 allows an attacker to take over any account, including administrator accounts, by exploiting a weak pseudo-random number generator (PRNG) used for generating password reset codes. The application uses random.randint for this purpose, which is not suitable for cryptographic use and can be cracked. An attacker with access to workflow tools can extract the PRNG output and predict future password reset codes, leading to a complete compromise of the application.

A vulnerability in the Dify Tools' Vanna module of the langgenius/dify repository allows for a Pandas Query Injection in the latest version. The vulnerability occurs in the function vn.gettrainingplangeneric(dfinformationschema), which does not properly sanitize user inputs before executing queries using the Pandas library. This can potentially lead to Remote Code Execution (RCE) if exploited.

langgenius/dify version v0.10.1 contains a vulnerability where there are no limits applied to the number of code guess attempts for password reset. This allows an unauthenticated attacker to reset owner, admin, or other user passwords within a few hours by guessing the six-digit code, resulting in a complete compromise of the application.

In langgenius/dify v0.10.1, the /forgot-password/resets endpoint does not verify the password reset code, allowing an attacker to reset the password of any user, including administrators. This vulnerability can lead to a complete compromise of the application.

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.

langgenius/dify version 0.9.1 contains a Server-Side Request Forgery (SSRF) vulnerability. The vulnerability exists due to improper handling of the apiendpoint parameter, allowing an attacker to make direct requests to internal network services. This can lead to unauthorized access to internal servers and potentially expose sensitive information, including access to the AWS metadata endpoint.

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.

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.

langgenius/dify version 0.10.1 contains a Server-Side Request Forgery (SSRF) vulnerability in the test functionality for the Create Custom Tool option via the REST API POST /console/api/workspaces/current/tool-provider/api/test/pre. Attackers can set the url in the servers dictionary in OpenAI's schema with arbitrary URL targets, allowing them to abuse the victim server's credentials to access unauthorized web resources.

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 'ssrfproxy', leading to an SSRF vulnerability. This issue was fixed in version 0.11.0.

A stored cross-site scripting (XSS) vulnerability exists in the latest version of langgenius/dify. The vulnerability is due to improper validation and sanitization of user input in SVG markdown support within the chatbot feature. An attacker can exploit this vulnerability by injecting malicious SVG content, which can execute arbitrary JavaScript code when viewed by an admin, potentially leading to credential theft.

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.

This vulnerability allows remote attackers to disclose sensitive information on affected installations of Dify. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the OAuth flow handling in the AppInitializer component. An attacker can force a redirection to a site that serves malicious content. An attacker can leverage this vulnerability to disclose information in the context of the application.

Dify AI Workflow oauthredirecturl Open Redirect Vulnerability. This vulnerability allows remote attackers to disclose sensitive information on affected installations of Dify. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.

The specific flaw exists within the OAuth flow handling in the AppInitializer component. An attacker can force a redirection to a site that serves malicious content. An attacker can leverage this vulnerability to disclose information in the context of the application. Was ZDI-CAN-29196.

A privilege escalation vulnerability exists in langgenius/dify version 0.9.1. This vulnerability allows a normal user to modify Orchestrate instructions for a chatbot created by an admin user. The issue arises because the application does not properly enforce access controls on the endpoint /console/api/apps/{chatbot-id}/model-config, allowing unauthorized users to alter chatbot configurations.

A vulnerability was determined in langgenius dify 1.13.0. Affected is the function router.replace of the file web/app/(shareLayout)/components/splash.tsx of the component Splash Layout. This manipulation of the argument redirecturl causes cross site scripting. The attack is possible to be carried out remotely. The exploit has been publicly disclosed and may be utilized. The vendor was contacted early about this disclosure but did not respond in any way.
