What is CVE-2026-109293?

An information disclosure vulnerability has been identified in Open WebUI versions prior to 0.11.4, where authenticated non-admin users with tool export permissions can exploit the application's API endpoint. By sending a GET request to /api/v1/tools/export, these users may gain access to the full Python source code of tools that are shared with them in a read-only manner. This exploitation can lead to the exposure of sensitive data, including embedded API keys and credentials, potentially compromising the security of the application and its data.
