CVE-2024-38828Network attack vector

Service interruption via byte-array request body handling

Published Nov 18, 2024 · Updated May 9, 2025

Uncontrolled resource consumption in Spring Framework 5.3.41 and earlier allows remote attackers to interrupt Spring MVC services. Request-body handling consumes excessive resources when a controller declares an @RequestBody byte[] parameter, but Spring has not disclosed the exact faulty operation. Exposure requires a network-reachable Spring MVC endpoint with that parameter shape; successful requests degrade availability without reported data access or modification.
