Vulnerabilities

A stored cross-site scripting (XSS) vulnerability exists in the `POST /api/prompts/share` endpoint of parisneo/lollms (latest version). The endpoint stores attacker-controlled `prompt_content` into `DBDirectMessage.content` without server-side sanitization. When a victim opens the direct message (DM) thread, the message is rendered by the DM UI through `MessageContentRenderer`, which uses `v-html` to insert rendered HTML into the DOM. The frontend sanitizer, which is regex-based, fails to comprehensively sanitize attacker-controlled HTML, allowing malicious payloads to execute in the victim's browser context. This vulnerability enables any authenticated user to send a malicious prompt-share message to another user's inbox, leading to arbitrary JavaScript execution, authenticated actions as the victim, exposure of same-origin application data, and potential account takeover.

A Cross-site Scripting (XSS) vulnerability was identified in the `from_dict` method of the `AppLollmsMessage` class in parisneo/lollms prior to version 2.2.0. The vulnerability arises from the lack of sanitization or HTML encoding of the `content` field when deserializing user-provided data. This allows an attacker to inject malicious HTML or JavaScript payloads, which can be executed in the context of another user's browser. Exploitation of this vulnerability can lead to account takeover, session hijacking, or wormable attacks.

A Stored Cross-Site Scripting (XSS) vulnerability was identified in the social feature of parisneo/lollms, affecting the latest version prior to 2.2.0. The vulnerability exists in the `create_post` function within `backend/routers/social/__init__.py`, where user-provided content is directly assigned to the `DBPost` model without sanitization. This allows attackers to inject and store malicious JavaScript, which is executed in the browsers of users viewing the Home Feed, including administrators. This can lead to account takeover, session hijacking, and wormable attacks. The issue is resolved in version 2.2.0.

In parisneo/lollms version 2.1.0, the application's session management is vulnerable to improper access control due to the use of a weak secret key for signing JSON Web Tokens (JWT). This vulnerability allows an attacker to perform an offline brute-force attack to recover the secret key. Once the secret key is obtained, the attacker can forge administrative tokens by modifying the JWT payload and resigning it with the cracked secret. This enables unauthorized users to escalate privileges, impersonate the administrator, and gain access to restricted endpoints. The issue is resolved in version 2.2.0.

A vulnerability in parisneo/lollms, up to and including version 2.2.0, allows unauthenticated users to upload and process files through the `/api/files/extract-text` endpoint. This endpoint does not enforce authentication, unlike other file-related endpoints, and lacks the `Depends(get_current_active_user)` dependency. This issue can lead to denial of service (DoS) through resource exhaustion, information disclosure, and violation of the application's documented security policies.

LoLLMs Web UI (lollms-webui), the web interface for Lord of Large Language and Multimodal Systems, contains a critical unauthenticated server-side request forgery (SSRF) flaw in its POST /api/proxy endpoint. An attacker with network access to the interface can send a crafted request that forces the server to issue arbitrary GET requests to attacker-chosen destinations. This enables access to internal-only services, scanning of the host's local network, and exfiltration of sensitive cloud instance metadata such as AWS or GCP IAM credentials. All known existing versions of lollms-webui are affected, and as of publication no patched release is available, so any deployed instance—particularly internet-exposed or cloud-hosted ones—is at risk. No confirmed in-the-wild exploitation is known, but a public security advisory exists and EPSS assigns an elevated 21.6% probability of exploitation within 30 days (97th percentile).

Do: No patched version is available yet, so mitigate by restricting access to the /api/proxy endpoint (e.g., via reverse-proxy authentication or ACLs) and limiting which instances are internet-exposed; on cloud-hosted deployments, block or restrict access to the instance metadata service (e.g., 169.254.169.254) to prevent IAM credential theft. Review server and cloud logs for unexpected outbound GET requests or metadata-service hits indicating exploitation, and upgrade as soon as a fixed lollms-webui release is published.

A path traversal vulnerability exists in the `install` and `uninstall` API endpoints of parisneo/lollms-webui version V12 (Strawberry). This vulnerability allows attackers to create or delete directories with arbitrary paths on the system. The issue arises due to insufficient sanitization of user-supplied input, which can be exploited to traverse directories outside the intended path.

parisneo/lollms-webui version 9.6 is vulnerable to Cross-Site Scripting (XSS) and Open Redirect due to inadequate input validation and processing of SVG files during the upload process. The XSS vulnerability allows attackers to embed malicious JavaScript code within SVG files, which is executed upon rendering, leading to potential credential theft and unauthorized data access. The Open Redirect vulnerability arises from insufficient URL validation within SVG files, enabling attackers to redirect users to malicious websites, thereby exposing them to phishing attacks, malware distribution, and reputation damage. These vulnerabilities are present in the application's functionality to send files to the AI module.

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 vulnerability in the discussion image upload function of the Lollms application, version v9.9, allows for the uploading of SVG files. Due to incomplete filtering in the sanitize_svg function, this can lead to cross-site scripting (XSS) vulnerabilities, which in turn pose a risk of remote code execution. The sanitize_svg function only removes script elements and 'on*' event attributes, but does not account for other potential vectors for XSS within SVG files. This vulnerability can be exploited when authorized users access a malicious URL containing the crafted SVG file.

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 path traversal vulnerability exists in the api open_personality_folder endpoint of parisneo/lollms-webui. This vulnerability allows an attacker to read any folder in the personality_folder on the victim's computer, even though sanitize_path is set. The issue arises due to improper sanitization of the personality_folder parameter, which can be exploited to traverse directories and access arbitrary files.

A path traversal vulnerability exists in the parisneo/lollms-webui repository, specifically in the `lollms_file_system.py` file. The functions `add_rag_database`, `toggle_mount_rag_database`, and `vectorize_folder` do not implement security measures such as `sanitize_path_from_endpoint` or `sanitize_path`. This allows an attacker to perform vectorize operations on `.sqlite` files in any directory on the victim's computer, potentially installing multiple packages and causing a crash.

A Local File Inclusion vulnerability exists in parisneo/lollms-webui versions below v9.8. The vulnerability is due to unverified path concatenation in the `serve_js` function in `app.py`, which allows attackers to perform path traversal attacks. This can lead to unauthorized access to arbitrary files on the server, potentially exposing sensitive information such as private SSH keys, configuration files, and source code.

In parisneo/lollms-webui version v9.8, the lollms_binding_infos is missing the client_id parameter, which leads to multiple security vulnerabilities. Specifically, the endpoints /reload_binding, /install_binding, /reinstall_binding, /unInstall_binding, /set_active_binding_settings, and /update_binding_settings are susceptible to CSRF attacks and local attacks. An attacker can exploit this vulnerability to perform unauthorized actions on the victim's machine.

parisneo/lollms-webui, in its latest version, is vulnerable to remote code execution due to an insecure dependency on llama-cpp-python version llama_cpp_python-0.2.61+cpuavx2-cp311-cp311-manylinux_2_31_x86_64. The vulnerability arises from the application's 'binding_zoo' feature, which allows attackers to upload and interact with a malicious model file hosted on hugging-face, leading to remote code execution. The issue is linked to a known vulnerability in llama-cpp-python, CVE-2024-34359, which has not been patched in lollms-webui as of commit b454f40a. The vulnerability is exploitable through the application's handling of model files in the 'bindings_zoo' feature, specifically when processing gguf format model files.

An absolute path traversal vulnerability exists in parisneo/lollms-webui v9.6, specifically in the `open_file` endpoint of `lollms_advanced.py`. The `sanitize_path` function with `allow_absolute_path=True` allows an attacker to access arbitrary files and directories on a Windows system. This vulnerability can be exploited to read any file and list arbitrary directories on the affected system.

A Path Traversal and Remote File Inclusion (RFI) vulnerability exists in the parisneo/lollms-webui application, affecting versions v9.7 to the latest. The vulnerability arises from insufficient input validation in the `/apply_settings` function, allowing an attacker to manipulate the `discussion_db_name` parameter to traverse the file system and include arbitrary files. This issue is compounded by the bypass of input filtering in the `install_binding`, `reinstall_binding`, and `unInstall_binding` endpoints, despite the presence of a `sanitize_path_from_endpoint(data.name)` filter. Successful exploitation enables an attacker to upload and execute malicious code on the victim's system, leading to Remote Code Execution (RCE).

A Cross-Site Request Forgery (CSRF) vulnerability exists in the 'Servers Configurations' function of the parisneo/lollms-webui, versions 9.6 to the latest. The affected functions include Elastic search Service (under construction), XTTS service, Petals service, vLLM service, and Motion Ctrl service, which lack CSRF protection. This vulnerability allows attackers to deceive users into unwittingly installing the XTTS service among other packages by submitting a malicious installation request. Successful exploitation results in attackers tricking users into performing actions without their consent.

A Cross-Site Request Forgery (CSRF) vulnerability exists in the XTTS server of parisneo/lollms version 9.6 due to a lax CORS policy. The vulnerability allows attackers to perform unauthorized actions by tricking a user into visiting a malicious webpage, which can then trigger arbitrary LoLLMS-XTTS API requests. This issue can lead to the reading and writing of audio files and, when combined with other vulnerabilities, could allow for the reading of arbitrary files on the system and writing files outside the permitted audio file location.

A Path Traversal vulnerability exists in the parisneo/lollms-webui, specifically within the 'add_reference_to_local_mode' function due to the lack of input sanitization. This vulnerability affects versions v9.6 to the latest. By exploiting this vulnerability, an attacker can predict the folders, subfolders, and files present on the victim's computer. The vulnerability is present in the way the application handles the 'path' parameter in HTTP requests to the '/add_reference_to_local_model' endpoint.

A Cross-Site Request Forgery (CSRF) vulnerability exists in the restart_program function of the parisneo/lollms-webui v9.6. This vulnerability allows attackers to trick users into performing unintended actions, such as resetting the program without their knowledge, by sending specially crafted CSRF forms. This issue affects the installation process, including the installation of Binding zoo and Models zoo, by unexpectedly resetting programs. The vulnerability is due to the lack of CSRF protection in the affected function.

A path traversal vulnerability exists in the parisneo/lollms application, specifically within the `sanitize_path_from_endpoint` and `sanitize_path` functions in `lollms_core\lollms\security.py`. This vulnerability allows for arbitrary file reading when the application is running on Windows. The issue arises due to insufficient sanitization of user-supplied input, enabling attackers to bypass the path traversal protection mechanisms by crafting malicious input. Successful exploitation could lead to unauthorized access to sensitive files, information disclosure, and potentially a denial of service (DoS) condition by including numerous large or resource-intensive files. This vulnerability affects the latest version prior to 9.6.

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 parisneo/lollms-webui, specifically within the 'copy_to_custom_personas' endpoint in the 'lollms_personalities_infos.py' file. This vulnerability allows attackers to read arbitrary files by manipulating the 'category' and 'name' parameters during the 'Copy to custom personas folder for editing' process. By inserting '../' sequences in these parameters, attackers can traverse the directory structure and access files outside of the intended directory. Successful exploitation results in unauthorized access to sensitive information.
