CVE-2026-49158 is an improper handling of highly compressed data vulnerability in the Apache Thrift Ruby bindings affecting versions before 0.24.0. The issue is described as a ZLIB decompression bomb in the Ruby THeaderTransport component, where highly compressed input can trigger disproportionate expansion during decompression. This creates a data amplification condition in which a relatively small compressed payload can consume excessive resources when processed by the vulnerable transport implementation.
