CVE-2026-48586
Description
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.
Statement
This Important vulnerability in Apache Thrift's handling of highly compressed data can lead to a denial of service. Remote, unauthenticated attackers could exploit this flaw by sending specially crafted compressed data, causing excessive resource consumption and disrupting the availability of services utilizing vulnerable Thrift bindings in Red Hat products.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
