Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in iePlexus Featured Content Gallery allows Stored XSS.This issue affects Featured Content Gallery: from n/a through 3.2.0.

A race condition vulnerability exists in the mintplex-labs/anything-llm repository, specifically within the user invite acceptance process. Attackers can exploit this vulnerability by sending multiple concurrent requests to accept a single user invite, allowing the creation of multiple user accounts from a single invite link intended for only one user. This bypasses the intended security mechanism that restricts invite acceptance to a single user, leading to unauthorized user creation without detection in the invite tab. The issue is due to the lack of validation for concurrent requests in the backend.

In mintplex-labs/anything-llm, an attacker can exploit improper input validation by sending a malformed JSON payload to the '/system/enable-multi-user' endpoint. This triggers an error that is caught by a catch block, which in turn deletes all users and disables the 'multi_user_mode'. The vulnerability allows an attacker to remove all existing users and potentially create a new admin user without requiring a password, leading to unauthorized access and control over the application.

mintplex-labs/anything-llm is vulnerable to improper input validation, allowing attackers to read and delete arbitrary files on the server. By manipulating the 'logo_filename' parameter in the 'system-preferences' API endpoint, an attacker can construct requests to read sensitive files or the application's '.env' file, and even delete files by setting the 'logo_filename' to the path of the target file and invoking the 'remove-logo' API endpoint. This vulnerability is due to the lack of proper sanitization of user-supplied input.

mintplex-labs/anything-llm is vulnerable to a relative path traversal attack, allowing unauthorized attackers with a default role account to delete files and folders within the filesystem, including critical database files such as 'anythingllm.db'. The vulnerability stems from insufficient input validation and normalization in the handling of file and folder deletion requests. Successful exploitation results in the compromise of data integrity and availability.

A mass assignment vulnerability exists in the `/api/invite/:code` endpoint of the mintplex-labs/anything-llm repository, allowing unauthorized creation of high-privileged accounts. By intercepting and modifying the HTTP request during the account creation process via an invitation link, an attacker can add a `role` property with `admin` value, thereby gaining administrative access. This issue arises due to the lack of property allowlisting and blocklisting, enabling the attacker to exploit the system and perform actions as an administrator.

A stored Cross-Site Scripting (XSS) vulnerability exists in the chat functionality of the mintplex-labs/anything-llm repository, allowing attackers to execute arbitrary JavaScript in the context of a user's session. By manipulating the ChatBot responses, an attacker can inject malicious scripts to perform actions on behalf of the user, such as creating a new admin account or changing the user's password, leading to a complete takeover of the AnythingLLM application. The vulnerability stems from the improper sanitization of user and ChatBot input, specifically through the use of `dangerouslySetInnerHTML`. Successful exploitation requires convincing an admin to add a malicious LocalAI ChatBot to their AnythingLLM instance.

A Denial of Service (DoS) vulnerability exists in the mintplex-labs/anything-llm repository when the application is running in 'just me' mode with a password. An attacker can exploit this vulnerability by making a request to the endpoint using the [validatedRequest] middleware with a specially crafted 'Authorization:' header. This vulnerability leads to uncontrolled resource consumption, causing a DoS condition.

A vulnerability in mintplex-labs/anything-llm allows users with manager roles to escalate their privileges to admin roles through a mass assignment issue. The '/admin/system-preferences' API endpoint improperly authorizes manager-level users to modify the 'multi_user_mode' system variable, enabling them to access the '/api/system/enable-multi-user' endpoint and create a new admin user. This issue results from the endpoint accepting a full JSON object in the request body without proper validation of modifiable fields, leading to unauthorized modification of system settings and subsequent privilege escalation.

In mintplex-labs/anything-llm, an improper input validation vulnerability allows attackers to escalate privileges by deactivating 'Multi-User Mode'. By sending a specially crafted curl request with the 'multi_user_mode' parameter set to false, an attacker can deactivate 'Multi-User Mode'. This action permits the creation of a new admin user without requiring a password, leading to unauthorized administrative access.
