Missing Release of Resource after Effective Lifetime
CVE-2024-52303
Summary
The package aiohttp is an asynchronous HTTP client/server framework for asyncio and Python. 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. 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. Those who use any middleware's with "aiohttp.web" should upgrade to receive a patch. This issue affects aiohttp package versions 3.10.6rc0 through 3.10.11rc0, and 3.11.0b0 through 3.11.0rc2.

CWE-772 - Missing Release Of Resource After Effective Lifetime
'Missing release of resource after effective lifetime' is a weakness that occurs when software doesn't sufficiently release a resource (e.g. memory, CPU, disk space, etc.) after it is used. If not addressed, attackers can launch a denial of service attack (by allocating a resource and not releasing it).
