In open-webui version 0.3.8, the endpoint `/models/upload` is vulnerable to arbitrary file write due to improper handling of user-supplied filenames. The vulnerability arises from the usage of `file_path = f"{UPLOAD_DIR}/{file.filename}"` without proper input validation or sanitization. An attacker can exploit this by manipulating the `file.filename` parameter to include directory traversal sequences, causing the resulting `file_path` to escape the intended `UPLOAD_DIR` and potentially overwrite arbitrary files on the system. This can lead to unauthorized modifications of system binaries, configuration files, or sensitive data, potentially enabling remote command execution.

In version v0.3.8 of open-webui/open-webui, the endpoint /api/pipelines/upload is vulnerable to arbitrary file write and delete due to unsanitized file.filename concatenation with CACHE_DIR. This vulnerability allows attackers to overwrite and delete system files, potentially leading to remote code execution.

Open WebUI is a self-hosted artificial intelligence platform designed to operate entirely offline. Prior to 0.9.5, the tool update endpoint (POST /api/v1/tools/id/{id}/update) is missing the workspace.tools permission check that is present on the tool create endpoint. This allows a user who has been explicitly denied tool management capabilities ( and who the administrator considers untrusted for code execution ) to replace a tool's server-side Python content and trigger execution, bypassing the intended workspace.tools security boundary. This vulnerability is fixed in 0.9.5.

A path traversal vulnerability exists in mintplex-labs/anything-llm versions up to and including 1.9.1, within the `AgentFlows` component. The vulnerability arises from improper handling of user input in the `loadFlow` and `deleteFlow` methods in `server/utils/agentFlows/index.js`. Specifically, the combination of `path.join` and `normalizePath` allows attackers to bypass directory restrictions and access or delete arbitrary `.json` files on the server. This can lead to information disclosure, such as leaking sensitive configuration files containing API keys, or denial of service by deleting critical files like `package.json`. The issue is resolved in version 1.12.1.

This affects versions of the package opencart/opencart from 4.0.0.0. A Zip Slip issue was identified via the marketplace installer due to improper sanitization of the target path, allowing files within a malicious archive to traverse the filesystem and be extracted to arbitrary locations. An attacker can create arbitrary files in the web root of the application and overwrite other existing files by exploiting this vulnerability.

A path traversal vulnerability in mintplex-labs/anything-llm allowed a manager to bypass the `normalizePath()` function, intended to defend against path traversal attacks. This vulnerability enables the manager to read, delete, or overwrite the 'anythingllm.db' database file and other files stored in the 'storage' directory, such as internal communication keys and .env secrets. Exploitation of this vulnerability could lead to application compromise, denial of service (DoS) attacks, and unauthorized admin account takeover. The issue stems from improper validation of user-supplied input in the process of setting a custom logo for the app, which can be manipulated to achieve arbitrary file read, deletion, or overwrite, and to execute a DoS attack by deleting critical files required for the application's operation.
