Gradio Project: Security Vulnerabilities
A path traversal vulnerability exists in the Gradio Audio component of gradio-app/gradio, as of version git 98cbcae. This vulnerability allows an attacker to control the format of the audio file, leading to arbitrary file content deletion. By manipulating the output format, an attacker can reset any file to an empty file, causing a denial of service (DOS) on the server.

A vulnerability in the dataframe component of gradio-app/gradio (version git 98cbcae) allows for a zip bomb attack. The component uses pd.read_csv to process input values, which can accept compressed files. An attacker can exploit this by uploading a maliciously crafted zip bomb, leading to a server crash and causing a denial of service.

A Regular Expression Denial of Service (ReDoS) vulnerability exists in the gradio-app/gradio repository, affecting the gr.Datetime component. The affected version is git commit 98cbcae. The vulnerability arises from the use of a regular expression `^(?:\s*now\s*(?:-\s*(\d+)\s*([dmhs]))?)?\s*$` to process user input. In Python's default regex engine, this regular expression can take polynomial time to match certain crafted inputs. An attacker can exploit this by sending a crafted HTTP request, causing the gradio process to consume 100% CPU and potentially leading to a Denial of Service (DoS) condition on the server.

Gradio is an open-source Python package that allows quick building of demos and web application for machine learning models, API, or any arbitrary Python function. Gradio's Access Control List (ACL) for file paths can be bypassed by altering the letter case of a blocked file or directory path. This vulnerability arises due to the lack of case normalization in the file path validation logic. On case-insensitive file systems, such as those used by Windows and macOS, this flaw enables attackers to circumvent security restrictions and access sensitive files that should be protected. This issue can lead to unauthorized data access, exposing sensitive information and undermining the integrity of Gradio's security model. Given Gradio's popularity for building web applications, particularly in machine learning and AI, this vulnerability may pose a substantial threat if exploited in production environments. This issue has been addressed in release version 5.6.0. Users are advised to upgrade. There are no known workarounds for this vulnerability.

Gradio is an open-source Python package designed to enable quick builds of a demo or web application. If File or UploadButton components are used as a part of Gradio application to preview file content, an attacker with access to the application might abuse these components to read arbitrary files from the application server. This issue has been addressed in release version 5.5.0 and all users are advised to upgrade. There are no known workarounds for this vulnerability.

In gradio <=4.42.0, the gr.DownloadButton function has a hidden server-side request forgery (SSRF) vulnerability. The reason is that within the save_url_to_cache function, there are no restrictions on the URL, which allows access to local target resources. This can lead to the download of local resources and sensitive information.

Gradio is an open-source Python package designed for quick prototyping. This vulnerability involves a **race condition** in the `update_root_in_config` function, allowing an attacker to modify the `root` URL used by the Gradio frontend to communicate with the backend. By exploiting this flaw, an attacker can redirect user traffic to a malicious server. This could lead to the interception of sensitive data such as authentication credentials or uploaded files. This impacts all users who connect to a Gradio server, especially those exposed to the internet, where malicious actors could exploit this race condition. Users are advised to upgrade to `gradio>=5` to address this issue. There are no known workarounds for this issue.

Gradio is an open-source Python package designed for quick prototyping. This vulnerability involves **insecure communication** between the FRP (Fast Reverse Proxy) client and server when Gradio's `share=True` option is used. HTTPS is not enforced on the connection, allowing attackers to intercept and read files uploaded to the Gradio server, as well as modify responses or data sent between the client and server. This impacts users who are sharing Gradio demos publicly over the internet using `share=True` without proper encryption, exposing sensitive data to potential eavesdroppers. Users are advised to upgrade to `gradio>=5` to address this issue. As a workaround, users can avoid using `share=True` in production environments and instead host their Gradio applications on servers with HTTPS enabled to ensure secure communication.

Gradio is an open-source Python package designed for quick prototyping. This vulnerability involves **Cross-Site Scripting (XSS)** on any Gradio server that allows file uploads. Authenticated users can upload files such as HTML, JavaScript, or SVG files containing malicious scripts. When other users download or view these files, the scripts will execute in their browser, allowing attackers to perform unauthorized actions or steal sensitive information from their sessions. This impacts any Gradio server that allows file uploads, particularly those using components that process or display user-uploaded files. Users are advised to upgrade to `gradio>=5` to address this issue. As a workaround, users can restrict the types of files that can be uploaded to the Gradio server by limiting uploads to non-executable file types such as images or text. Additionally, developers can implement server-side validation to sanitize uploaded files, ensuring that HTML, JavaScript, and SVG files are properly handled or rejected before being stored or displayed to users.

Gradio is an open-source Python package designed for quick prototyping. This vulnerability is a **lack of integrity check** on the downloaded FRP client, which could potentially allow attackers to introduce malicious code. If an attacker gains access to the remote URL from which the FRP client is downloaded, they could modify the binary without detection, as the Gradio server does not verify the file's checksum or signature. Any users utilizing the Gradio server's sharing mechanism that downloads the FRP client could be affected by this vulnerability, especially those relying on the executable binary for secure data tunneling. There is no direct workaround for this issue without upgrading. However, users can manually validate the integrity of the downloaded FRP client by implementing checksum or signature verification in their own environment to ensure the binary hasn't been tampered with.
