Kerentanan Improper Handling of Highly Compressed Data (Data Amplification) pada aiohttp. Skor CVSS 3.1 7.5 (High) menurut NVD.

Deskripsi (NVD)

AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python. Prior to 3.14.1, during cleanup it is possible for a compressed request body to be decompressed into memory in one chunk. An attacker may be able to send a compressed payload in specific situations that could be decompressed into memory, potentially leading to DoS (a zip bomb edge case). This vulnerability is fixed in 3.14.1.
