CVE-2026-3260

Rejected denial-of-service claim

Published Mar 24, 2026 · Updated Mar 24, 2026

Undertow does not permit the claimed remote denial of service because its default entity-size limit drops oversized request bodies. The rejected report alleged that GET multipart bodies reached parameter parsing and disk storage, but the server applies the configurable limit to every request method before one oversized body can exhaust memory. The assigning CNA therefore withdrew the affected-product, weakness, and severity assertions, so no supported Red Hat deployment is currently classified as vulnerable.
