CVE-2026-48586

A flaw was found in Apache Thrift. This vulnerability, categorized as improper handling of highly compressed data (also known as data amplification), allows a remote attacker to cause a Denial of Service (DoS) by sending specially crafted, highly compressed data. The affected component fails to properly manage the expansion of this data, leading to resource exhaustion and system unavailability.

7.5 (High)
