Zip bomb vulnerability in Envoy

Published: 3/6/2024Modified: 10/14/2025
Also known as:GHSA-75hv-2jjj-89hhBIT-envoy-2022-29225

Description

Envoy is a cloud-native high-performance proxy. In versions prior to 1.22.1 secompressors accumulate decompressed data into an intermediate buffer before overwriting the body in the decode/encodeBody. This may allow an attacker to zip bomb the decompressor by sending a small highly compressed payload. Maliciously constructed zip files may exhaust system memory and cause a denial of service. Users are advised to upgrade. Users unable to upgrade may consider disabling decompression.
