When using "web.static(..., show_index=True)", the resulting index pages do not escape file names. If users can upload files with arbitrary filenames to the static directory, the server is vulnerable to cross-site scripting (XSS) attacks.	Story Points:	---

Description Robb Gatica 2024-04-18 20:28:45 UTC

aiohttp is an asynchronous HTTP client/server framework for asyncio and Python. A XSS vulnerability exists on index pages for static file handling. This vulnerability is fixed in 3.9.4. We have always recommended using a reverse proxy server (e.g. nginx) for serving static files. Users following the recommendation are unaffected. Other users can disable `show_index` if unable to upgrade.
