RHSA-2026:47172

Vulnerability from csaf_redhat - Published: 2026-07-30 01:40 - Updated: 2026-09-11 18:42

Summary

Red Hat Security Advisory: Red Hat build of Quarkus 3.33.2.SP3 security update

Severity

Important

Scope

15 vulnerabilities in this advisory, including CVE-2026-16308.

CVE-2026-16308

A flaw was found in Quarkus REST. An unauthenticated remote attacker can exploit this vulnerability by sending a crafted multipart/form-data request with an excessively large header section. This unbounded accumulation of MIME part-header bytes can exhaust the Java Virtual Machine (JVM) heap memory, leading to an OutOfMemoryError. The primary consequence is a denial of service, causing the application to crash.

7.5 (High)
