#vulnerability

### Impact **What kind of vulnerability is it? Who is impacted?** This vulnerability is a **data validation issue** in the Gradio `Dropdown` component's pre-processing step. Even if the `allow_custom_value` parameter is set to `False`, attackers can bypass this restriction by sending custom requests with arbitrary values, effectively breaking the developer’s intended input constraints. While this alone is not a severe vulnerability, it can lead to more critical security issues, particularly when paired with other vulnerabilities like file downloads from the user's machine. ### Patches Yes, this issue is addressed in `gradio>=5.0`. Please upgrade to the latest version to resolve the problem. ### Workarounds **Is there a way for users to fix or remediate the vulnerability without upgrading?** To mitigate the issue without upgrading, developers can add manual validation in their prediction function to check the received values against the allowed dropdown values before processing th...

### Impact **What kind of vulnerability is it? Who is impacted?** 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. ### Patches Yes, please upgrade to `gradio>=5` to address this issue. ### Workarounds **Is there a way for users to fix or remediate the vulnerability without upgrading?** 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 ...

### Impact **What kind of vulnerability is it? Who is impacted?** 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. ### Patches Yes, please upgrade to `gradio>=5` to address this issue. ### Workarounds **Is there a way for users to fix or remediate the vulnerability without upgrading?** 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.

### Impact **What kind of vulnerability is it? Who is impacted?** 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. ### Patches Yes, please upgrade to `gradio>=5` to address this issue.

### Impact **What kind of vulnerability is it? Who is impacted?** This vulnerability involves a **timing attack** in the way Gradio compares hashes for the `analytics_dashboard` function. Since the comparison is not done in constant time, an attacker could exploit this by measuring the response time of different requests to infer the correct hash byte-by-byte. This can lead to unauthorized access to the analytics dashboard, especially if the attacker can repeatedly query the system with different keys. ### Patches Yes, please upgrade to `gradio>4.44` to mitigate this issue. ### Workarounds **Is there a way for users to fix or remediate the vulnerability without upgrading?** To mitigate the risk before applying the patch, developers can manually patch the `analytics_dashboard` dashboard to use a **constant-time comparison** function for comparing sensitive values, such as hashes. Alternatively, access to the analytics dashboard can be disabled.

### Impact **What kind of vulnerability is it? Who is impacted?** This is a **data validation vulnerability** affecting several Gradio components, which allows arbitrary file leaks through the post-processing step. Attackers can exploit these components by crafting requests that bypass expected input constraints. This issue could lead to sensitive files being exposed to unauthorized users, especially when combined with other vulnerabilities, such as issue TOB-GRADIO-15. The components most at risk are those that return or handle file data. ### Vulnerable Components: 1. **String to FileData:** DownloadButton, Audio, ImageEditor, Video, Model3D, File, UploadButton. 2. **Complex data to FileData:** Chatbot, MultimodalTextbox. 3. **Direct file read in preprocess:** Code. 4. **Dictionary converted to FileData:** ParamViewer, Dataset. ### Exploit Scenarios: 1. A developer creates a Dropdown list that passes values to a DownloadButton. An attacker bypasses the allowed inputs, sends an arbi...

### Impact 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. **Who is impacted?** 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. ### Patches Yes, please upgrade to `gradio>=5.0`, which includes a fix to verify the integrity of the downloaded binary. ### Workarounds 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 ...

### Impact What kind of vulnerability is it? Who is impacted? This vulnerability involves data exposure due to the enable_monitoring flag not properly disabling monitoring when set to False. Even when monitoring is supposedly disabled, an attacker or unauthorized user can still access the monitoring dashboard by directly requesting the /monitoring endpoint. This means that sensitive application analytics may still be exposed, particularly in environments where monitoring is expected to be disabled. Users who set enable_monitoring=False to prevent unauthorized access to monitoring data are impacted. ### Patches Yes, please upgrade to gradio>=4.44 to address this issue.

### Impact **What kind of vulnerability is it? Who is impacted?** This vulnerability relates to **Server-Side Request Forgery (SSRF)** in the `/queue/join` endpoint. Gradio’s `async_save_url_to_cache` function allows attackers to force the Gradio server to send HTTP requests to user-controlled URLs. This could enable attackers to target internal servers or services within a local network and possibly exfiltrate data or cause unwanted internal requests. Additionally, the content from these URLs is stored locally, making it easier for attackers to upload potentially malicious files to the server. This impacts users deploying Gradio servers that use components like the Video component which involve URL fetching. ### Patches Yes, please upgrade to `gradio>=5` to address this issue. ### Workarounds **Is there a way for users to fix or remediate the vulnerability without upgrading?** As a workaround, users can disable or heavily restrict URL-based inputs in their Gradio application...

### Impact **What kind of vulnerability is it? Who is impacted?** 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. ### Patches Yes, please upgrade to `gradio>=4.44` to address this issue. ### Workarounds **Is there a way for users to fix or remediate the vulnerability without upgrading?** As a workaround, developers can sanitize the file paths and ensure that components are not stored in publicly accessible directories.
