CVE-2024-22233Network attack vector

Unauthenticated application service interruption

Published Jan 22, 2024 · Updated Jun 20, 2025

Denial of service in Spring Framework 6.0.15 and 6.1.2 allows remote attackers to interrupt applications with crafted HTTP requests. Spring has not published the affected method or the incorrect operation performed while processing those requests. Exposure requires Spring MVC and Spring Security 6.1.6 or later or 6.2.1 or later on the classpath; successful requests consume enough resources to interrupt service.
