In versions 3.13.2 and below, handling of chunked messages can result in excessive blocking CPU usage when receiving a large number of chunks. If an application makes use of the request.read() method in an endpoint, it may be possible for an attacker to cause the server to spend a moderate amount of blocking CPU time (e.g. 1 second) while processing the request. This could potentially lead to DoS as the server would be unable to handle other requests during that time. This issue is fixed in version 3.13.3."}], "lastModified": "2026-01-14T19:17:34.960", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:aiohttp:aiohttp:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "715B630E-B141-4247-A920-3FFBD8045A05", "versionEndExcluding": "3.13.3"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
