What is CVE-2024-47166?
CVE-2024-47166 is a low-severity path traversal vulnerability in Gradio Project Gradio, published on 10 Oct 2024. Any signed-in user can exploit it over the network, with no action from the victim.
Official description
Gradio is an open-source Python package designed for quick prototyping. This vulnerability involves a **one-level read path traversal** in the `/custom_component` endpoint. Attackers can exploit this flaw to access and leak source code from custom Gradio components by manipulating the file path in the request. Although the traversal is limited to a single directory level, it could expose proprietary or sensitive code that developers intended to keep private. This impacts users who have developed custom Gradio components and are hosting them on publicly accessible servers. Users are advised to upgrade to `gradio>=4.44` to address this issue. As a workaround, developers can sanitize the file paths and ensure that components are not stored in publicly accessible directories.
Weakness: CWE-22
