Severity: HIGH
Package: aiohttp @ 3.14.1
Fixed in: 3.14.3

AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python. Prior to 3.14.3, an out-of-bounds heap read could occur in the C response parser while building an error message for a malformed response. An attacker controlled server, or possibly an accidental response, could trigger a DoS in the client. The vulnerable path was error message construction in aiohttp/_http_parser.pyx, where an llhttp error-position pointer was used to build a snippet for malformed chunked responses

Duplicate of #584 — filed by the supply-chain scanner against the pre-fix dependency set. The bump landed in 611a1d6 (aiohttp 3.14.3, pyasn1 0.6.4, cryptography 50.0.0; verified installed) with per-CVE exploitability rationale on the original issue. The next scheduled scan runs against the fixed lockfile.
