A CORS misconfiguration in parisneo/lollms-webui prior to version 10 allows attackers to steal sensitive information such as logs, browser sessions, and settings containing private API keys from other services. This vulnerability can also enable attackers to perform actions on behalf of a user, such as deleting a project or sending a message. The issue impacts the confidentiality and integrity of the information.

A Cross-Site Request Forgery (CSRF) vulnerability exists in the `install_comfyui` endpoint of the `lollms_comfyui.py` file in the parisneo/lollms-webui repository, versions v9.9 to the latest. The endpoint uses the GET method without requiring a client ID, allowing an attacker to trick a victim into installing ComfyUI. If the victim's device does not have sufficient capacity, this can result in a crash.

A vulnerability in parisneo/lollms-webui version 9.8 allows for a Denial of Service (DOS) attack when uploading an audio file. If an attacker appends a large number of characters to the end of a multipart boundary, the system will continuously process each character, rendering lollms-webui inaccessible. This issue is exacerbated by the lack of Cross-Site Request Forgery (CSRF) protection, enabling remote exploitation. The vulnerability leads to service disruption, resource exhaustion, and extended downtime.

A Cross-site Scripting (XSS) vulnerability exists in the chat functionality of parisneo/lollms-webui in the latest version. This vulnerability allows an attacker to inject malicious scripts via chat messages, which are then executed in the context of the user's browser.

A Cross-Site Request Forgery (CSRF) vulnerability exists in the clear_personality_files_list function of the parisneo/lollms-webui v9.6. The vulnerability arises from the use of a GET request to clear personality files list, which lacks proper CSRF protection. This flaw allows attackers to trick users into performing actions without their consent, such as deleting important files on the system. The issue is present in the application's handling of requests, making it susceptible to CSRF attacks that could lead to unauthorized actions being performed on behalf of the user.

A remote code execution (RCE) vulnerability exists in the '/install_extension' endpoint of the parisneo/lollms-webui application, specifically within the `@router.post("/install_extension")` route handler. The vulnerability arises due to improper handling of the `name` parameter in the `ExtensionBuilder().build_extension()` method, which allows for local file inclusion (LFI) leading to arbitrary code execution. An attacker can exploit this vulnerability by crafting a malicious `name` parameter that causes the server to load and execute a `__init__.py` file from an arbitrary location, such as the upload directory for discussions. This vulnerability affects the latest version of parisneo/lollms-webui and can lead to remote code execution without requiring user interaction, especially when the application is exposed to an external endpoint or operated in headless mode.

A path traversal vulnerability exists in the 'cyber_security/codeguard' native personality of the parisneo/lollms-webui, affecting versions up to 9.5. The vulnerability arises from the improper limitation of a pathname to a restricted directory in the 'process_folder' function within 'lollms-webui/zoos/personalities_zoo/cyber_security/codeguard/scripts/processor.py'. Specifically, the function fails to properly sanitize user-supplied input for the 'code_folder_path', allowing an attacker to specify arbitrary paths using '../' or absolute paths. This flaw leads to arbitrary file read and overwrite capabilities in specified directories without limitations, posing a significant risk of sensitive information disclosure and unauthorized file manipulation.

A path traversal and arbitrary file upload vulnerability exists in the parisneo/lollms-webui application, specifically within the `@router.get("/switch_personal_path")` endpoint in `./lollms-webui/lollms_core/lollms/server/endpoints/lollms_user.py`. The vulnerability arises due to insufficient sanitization of user-supplied input for the `path` parameter, allowing an attacker to specify arbitrary file system paths. This flaw enables direct arbitrary file uploads, leakage of `personal_data`, and overwriting of configurations in `lollms-webui`->`configs` by exploiting the same named directory in `personal_data`. The issue affects the latest version of the application and is fixed in version 9.4. Successful exploitation could lead to sensitive information disclosure, unauthorized file uploads, and potentially remote code execution by overwriting critical configuration files.

A path traversal vulnerability exists in the parisneo/lollms-webui application, specifically within the `lollms_core/lollms/server/endpoints/lollms_binding_files_server.py` and `lollms_core/lollms/security.py` files. Due to inadequate validation of file paths between Windows and Linux environments using `Path(path).is_absolute()`, attackers can exploit this flaw to read any file on the system. This issue affects the latest version of LoLLMs running on the Windows platform. The vulnerability is triggered when an attacker sends a specially crafted request to the `/user_infos/{path:path}` endpoint, allowing the reading of arbitrary files, as demonstrated with the `win.ini` file. The issue has been addressed in version 9.5 of the software.

A path traversal vulnerability exists in the parisneo/lollms-webui version 9.3 on the Windows platform. Due to improper validation of file paths between Windows and Linux environments, an attacker can exploit this vulnerability to delete any file on the system. The issue arises from the lack of adequate sanitization of user-supplied input in the 'del_preset' endpoint, where the application fails to prevent the use of absolute paths or directory traversal sequences ('..'). As a result, an attacker can send a specially crafted request to the 'del_preset' endpoint to delete files outside of the intended directory.
