Description
### Summary A XSS vulnerability exists on index pages for static file handling. ### Details 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 XSS attacks. ### Workaround 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. ----- Patch: https://github.com/aio-libs/aiohttp/pull/8319/files
