"statement": "A flaw was found in aiohttp, an asynchronous HTTP client/server framework for Python. Attacker-controlled input passed into multipart or payload headers can inject additional HTTP headers via CRLF sequences. Exploitation requires that the application explicitly passes user-controlled strings into `MultipartWriter.append(headers=...)` or `Payload.headers`, which the upstream project describes as an unlikely scenario. Red Hat rates this as Low impact due to the specific preconditions required for exploitation. The NIST CVSSv3 score of 7.5 (High) rates availability impact as High, but this is a header injection issue affecting integrity, not availability \u2014 the Red Hat CVSSv3 score of 4.8 with Attack Complexity: High more accurately reflects the exploitation requirements.", "threat_severity": "Low"}
