Resolved: https://github.com/plabayo/rama/commit/89ddff578fd78bbebec99482d7030f28c07757a3 ## Summary `plabayo/rama` contains a stored/reflected cross-site scripting issue in the `ServeDir` HTML directory listing feature. When `ServeDir` is configured with `DirectoryServeMode::HtmlFileList`, file names and URI path components are inserted directly into generated HTML without HTML escaping. If an attacker can create or influence a file or directory name inside a served directory, they may inject HTML or JavaScript into the directory listing page. This can execute script in the browser of any user who visits the affected directory listing. ## Affected Repository `plabayo/rama` ## Affected Component `rama-http/src/service/fs/serve_dir/open_file.rs` ## Root Cause The HTML directory listing is constructed using string formatting and inserts untrusted values directly into HTML. The directory listing row includes the file or directory name in both the link text and the `href` attribute: rows.push(format!( "{5} {0}{3}{4}", entry.name, uri.path().trim_end_matches('/'), ... )); The navigation breadcrumb also inserts URI path parts into generated HTML: nav_parts.push(format!("{part}")); The page title and heading also include the current URI path: Directory listing for .{0}

Directory listing for .{0}

These values are not HTML-escaped before being embedded into the generated page. ## Security Impact If an application uses `ServeDir` with `DirectoryServeMode::HtmlFileList`, an attacker who can create or influence file names inside the served directory can inject HTML or JavaScript into the generated directory listing. Possible impact includes: - Script execution in the browser of users viewing the directory listing - Session or token theft if the application uses cookies or browser-accessible
