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. CREATE(Triage):(User=admin) CVE-2024-27306 (https://nvd.nist.gov/vuln/detail/CVE-2024-27306)
