### 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 ...

AList is a file list program that supports multiple storages. AList contains a reflected cross-site scripting vulnerability in helper.go. The endpoint /i/:link_name takes in a user-provided value and reflects it back in the response. The endpoint returns an application/xml response, opening it up to HTML tags via XHTML and thus leading to a XSS vulnerability. This vulnerability is fixed in 3.29.0.

Ubuntu Security Notice 7061-1 - Hunter Wittenborn discovered that Go incorrectly handled the sanitization of environment variables. An attacker could possibly use this issue to run arbitrary commands. Sohom Datta discovered that Go did not properly validate backticks as Javascript string delimiters, and did not escape them as expected. An attacker could possibly use this issue to inject arbitrary Javascript code into the Go template.
