CVE-2024-52303
HIGH7.5EPSS 0.42%aiohttp has a memory leak when middleware is enabled when requesting a resource with a non-allowed method
發布日:2024/11/18修改日:2026/2/4
描述
### Summary A memory leak can occur when a request produces a `MatchInfoError`. This was caused by adding an entry to a cache on each request, due to the building of each `MatchInfoError` producing a unique cache entry. ### Impact If the user is making use of any middlewares with `aiohttp.web` then it is advisable to upgrade immediately. An attacker may be able to exhaust the memory resources of a server by sending a substantial number (100,000s to millions) of such requests. ----- Patch: https://github.com/aio-libs/aiohttp/commit/bc15db61615079d1b6327ba42c682f758fa96936
