+- CVE-2024-23829
+- GHSA-8qpw-xqxj-h4r2
+details: aiohttp is an asynchronous HTTP client/server framework for asyncio and Python.
+  Security-sensitive parts of the Python HTTP parser retained minor differences in
+  allowable character sets, that must trigger error handling to robustly match frame
+  boundaries of proxies in order to protect against injection of additional requests.
+  Additionally, validation could trigger exceptions that were not handled consistently
+  with processing of other malformed input.  Being more lenient than internet standards
+  require could, depending on deployment environment, assist in request smuggling.
+  The unhandled exception could cause excessive resource consumption on the application
+  server and/or its logging facilities. This vulnerability exists due to an incomplete
+  fix for CVE-2023-47627. Version 3.9.2 fixes this vulnerability.
